What is the value of x in the equation 8 + 4 = 2 (x minus 1)?

Tanzania [10]

Answer:

x = 7

Explanation:

8 + 4 = 2 (x − 1)

Simplify both sides of the equation

8 + 4 = 2(x − 1)

8 + 4 = (2)(x) + (2)(−1) (Distribute)

8 + 4 = 2x + −2

(8 + 4) = 2x − 2 (Combine Like Terms)

12 = 2x − 2

12 = 2x − 2

Flip the equation

2x − 2 = 12

Add 2 to both sides

2x − 2 + 2 = 12 + 2

2x = 14

Divide both sides by 2

2x / 2 = 14 / 2

x = 7

Solve for the indicated variable. Include all of your work in your answer. Submit your solution.

levacccp [35]

Answer:

The answer is $L=\frac{A}{W}$

Step-by-step explanation:

In order to determine the answer, we have to know about equation. In an equation, we have variables, some of them depend on the others. If we want to know the value of one variable ( the dependent variable), we have to free it in any side of the equation.

In this case, we want to know the value of "L" variable. So we free that variable to the right side of the equation.

$A=LW$

We divide each side by "W":

$\frac{A}{W}=\frac{LW}{W}$

We simplify the "W" in the right side:

$\frac{A}{W}=L$

Finally, the solution for "L" is :

$L=\frac{A}{W}$

Solve the following system using the substitution method. Enter your answer as an ordered pair in the form (x, y)(x,y).

slamgirl [31]

The value of ordered pair of (x,y) is (-2, -3)

<h3>How to solve the equation by substitution method ? </h3>

x - 5y = 13

4x - 3y = 1

Solve the equation for x

x - 5y = 13

Move '5y' to R.H.S and change it's sign

x=13+5y

Substitute the given value of X into the equation

4x - 3y = 1

4(13+5y)-3y = 1

Solve the equation for y

distribute 4 through the parentheses

52+20y -3y =1

Collect like terms

52+17y = 1

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

17y = 1 - 52

Calculate

17y = - 51

Divide both sides of the equation by 17

17y/17 = -51/17

Calculate

y = -3

Now, substitute the given value of y into the equation

x = 13 + 5y

x= =13+5x(-3)

Solve the equation for x

Multiply the numbers

= 13 - 15

Calculate the difference

= -2

The possible solution of the system is the ordered pair

( x , y )

( x , y ) = ( - 2 , - 3 )

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

Check if the given ordered pair is the solution of the system of equation

-2-5×(-3)=15

4×(-2)-3×(-3)=1

Simplify the equalities

13 = 13

1=1

Since all of the equalities are true, the ordered pair is the solution of the system

( x , y ) = ( - 2 , - 3 )

Therefore the value of ordered pair of (x,y) is (-2, -3)

The complete question is : Solve the system by substitution. x−5y=13 4x−3y=1 Enter your answer as an ordered pair (x,y).
