Question

20 = -2x-6(-5x+20)

?????????

Answer 1

x=5 hope this helps feel free to ask any more question i would be glad to help

Explanation:

-6(-5x+20)-2x=20

move all terms to the left:

-6(-5x+20)-2x-(20)=0

add all the numbers together, and all the variables

-2x-6(-5x+20)-20=0

multiply parentheses

-2x+30x-120-20=0

add all the numbers together, and all the variables

28x-140=0

move all terms containing x to the left, all other terms to the right

28x=140

x=140/28

x=5

Answer 2

x=5

Explanation:

20 = -2x-6(-5x+20)

distribute

20 = -2x -6*(-5x) -6*20

20 = -2x +30x -120

combine like terms

20 = 28x-120

add 120 to each side

20+120 = 28x-120+120

140 = 28x

divide by 28

140/28 = 28x/28

140/28 = x

5 =x
