Question

Solve the following equation. -8(-x-5)=40+8x

Answer 1

all the values

Explanation:

`-8(-x-5)=40+8x\\\\-x-5=(40)/(-8)+ (8x)/(-8) \\\\-x-5=-5-x\\\\-x-5=-x-5\\\\-x=-x-5+5\\\\-x=-x+0\\\\-x=-x\\`

`-1(-x)=-1(-x)\\\\x=x`

so all the values for x are solutions

Answer 2

40=40 so the equation is true

Explanation:

-8(-x-5)=40+8x

8x +40 = 40 + 8x

if you cancle out the 8x on both sides then it will be 40 = 40
