Simplifying

7x + -10x + 18 + 2x = -5

Reorder the terms:

18 + 7x + -10x + 2x = -5

Combine like terms: 7x + -10x = -3x

18 + -3x + 2x = -5

Combine like terms: -3x + 2x = -1x

18 + -1x = -5

Solving

18 + -1x = -5

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-18' to each side of the equation.

18 + -18 + -1x = -5 + -18

Combine like terms: 18 + -18 = 0

0 + -1x = -5 + -18

-1x = -5 + -18

Combine like terms: -5 + -18 = -23

-1x = -23

Divide each side by '-1'.

x = 23

Simplifying

x = 23

Slope -8 and y intercept 7

max2010maxim [7]

Answer:

The equation of Line is y = - 8x + 7

Step-by-step explanation:

Given as :

The slop of line is - 8

And The y intercept is 7

As the equation of line is y = mx + c

For y intercept , x = 0

So, With y intercept and slop ,

7 = (-8)× (0)+ c

Or, c = 7

So the equation of line is

y = mx + c

I.e y = ( - 8 ) x + 7

Hence The equation of Line is y = - 8x + 7 Answer

0=-20.5x+16.35x-0.1245

Pachacha [2.7K]

The value of x in the given equation $-20.5x+16.35x -0.1245 = 0\\$ is 0.03

<u>Step-by-step explanation:</u>

The given equation is that $-20.5x+16.35x -0.1245 = 0\\$

<u>The steps to be followed to solve the equation are :</u>

Add the like terms together to reduce the equation in a simplified form.

Here, there are two x terms and they must be reduced to a single term.

For this, add the both terms together so that the equation is simplified into one x term and a constant term.

⇒ $(-20.5x+16.35x) - 0.1245 = 0$

⇒ $4.15x-0.1245 = 0$

To eliminate the constant term on the left side of the equation, add 0.1245 on both sides.

⇒ $4.15x -0.1245+0.1245 = 0.1245$

⇒ $4.15x = 0.1245$

Now, the equation is further simplified by dividing 4.15 on both sides,

⇒ $4.15x / 4.15 = 0.1245/4.15$

⇒ $x = 0.03$

Therefore, the value of x is 0.03
