Answer:

<h3>\boxed{ \bold{ \mathsf{ \purple{x  =  - 13}}}}</h3>

Step-by-step explanation:

\mathsf{2x - 3x + 5 = 18}

Collect like terms

\mathsf{ - x + 5 = 18}

Move constant to R.H.S and change it's sign

\mathsf{ - x = 18 - 5}

Calculate the difference

- x = 13

Change the signs on both sides of the equation

\mathsf{x =  - 13}

---------------------------------------------------------------

\blue{ \mathsf{verification}}

\mathsf{LHS \:  \:  \:  \:  \:  \: \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \: \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:     RHS}

\mathsf{2x - 3x + 5 \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:       18}

\mathsf{ = 2 \times ( - 13) - 3 \times ( - 13) + 5}

\mathsf{ - 26 + 39 + 5}

\mathsf{ = 13  + 5}

= 18

Thus, LHS = RHS

hope I helped!

Best regards!

Hi my lil bunny!

Let's solve your equation step-by-step.

2x-3x+5=18

Step 1: Simplify both sides of the equation.

2x-3x+5=18\\2x + -3x + 5 = 18

( 2x + -3x ) + ( 5) = 18 (Combine Like Terms)

-x + 5 = 18\\-x + 5 = 18

Step 2: Subtract 5 from both sides.

-x + 5 - 5 = 18 - 5 \\-x = 13

Step 3: Divide both sides by -1.

\frac{-x}{-1} = \frac{13}{-1} \\x = -13

Answer : \boxed {x = -13}

Step-by-step explanation:

Im going to assume the question says what is 1% of 7.

so 100%=7

divide my 10 to get to 10%

10%=0.7

do the same thing.

1%=0.07

you just go backwards when dividing by 10.

Answer:

Therefore,

(x , y)                YES / NO

(-4, -5)           Yes, It is a Solution.

(1 , - 3)           No, not a Solution.

(9 , 6)            No, not a Solution.

(-6 , 2)           No, not a Solution.

Step-by-step explanation:

Given:

4x-7y=19

To Determine:

Given ordered pair is a solution or not ?

Solution:

For (-4,-5)  

Substitute x = -4 and y = -5 in above equation

Left Hand Side   = 4 × (-4) - 7 × (-5)

                           = -16+35

                           = 19

Right Hand Side = 19

Left Hand Side = Right Hand Side  

Satisfied

Hence (-4, -5) is the SOLUTION to 4x - 7y =19  (YES)

For (1, -3)  

Substitute x = 1 and y = -3 in above equation

Left Hand Side = 4 × (1) - 7 × (-3)

                         = 25

Right Hand Side = 19

Left Hand Side ≠ Right Hand Side  

Not Satisfied

Hence (1, -3) is NOT the Solution to 4x - 7y =19  (NO)

For (9, 6)  

Substitute x = 9 and y = 6 in above equation

Left Hand Side = 4 × (9) - 7 × (6)

                         = -6

Right Hand Side = 19

Left Hand Side ≠ Right Hand Side  

Not Satisfied

Hence (9, 6) is NOT the Solution to 4x - 7y =19  (NO)

For (-6, 2)  

Substitute x = -6 and y = 2 in above equation

Left Hand Side = 4 × (-6) - 7 × (2)

                         = -38

Right Hand Side = 19

Left Hand Side ≠ Right Hand Side  

Not Satisfied

Hence (-6, 2) is NOT the Solution to 4x - 7y =19  (NO)

Therefore,

(x , y)                YES / NO

(-4, -5)           Yes, It is a Solution.

(1 , - 3)           No, not a Solution.

(9 , 6)            No, not a Solution.

(-6 , 2)           No, not a Solution.
