Question

Y=-5x -6
10x + 2y = -12
solve each system by substitution
​

Answer 1

x=0

Explanation:

y=-5x -6

10x + 2y = -12

Substitute y into the equation:

• 10x+2(5x-6)=-12

Use distributive property

• 10x+10x-12=-12

Add like terms

• 20x-12=-12

Add 12 to both sides of the equation

• 20x=0

divide each side by 0

• x=0
