Solve each system by substitution.<br> y=5x-7<br> -3x-2y=-12<br> Type in your solution (x,y)
aksik [14]
<h3>Given system :</h3>

y = 5x - 7 \\  - 3x - 2y =  - 12

<h3>Solution to the system :</h3>

Substitute the given value of y into the equation -3x-2y=-12

- 3x - 2(5x - 7) =  - 12

Distribute -2 through the parentheses

- 3x - 10x + 14 =  - 12

Collect like terms

- 13x + 14 =  - 12

Move the constant to the right-hand side and change its sign

- 13x =  - 12 - 14

Calculate the sum and divide both sides of equation by -13

x = 2

Now, Substitute the given value of x into y=5x-7

y = 5(2) - 7

Multiply the numbers

y = 10 - 7

Subtract the numbers

y = 3

The possible solution of the system is the ordered pair (x,y)

(x,y)=(2,3)
