Question

- 5 ( 4x + 2 ) + 2x + 1 = - 151

Answer 1

Answer:

-5 * (4x + 2) + 2x + 1 = -151

-20x - 10 + 2x + 1 = -151

-18x - 9 = -151

-18x = -142

x = 71/9 = 7 8/9

Answer 2

Answer:

x=140/-18

x=-7+7/9

Step-by-step explanation:

-5(4x-2)+2x+1=151

We move all terms to the left:

-5(4x-2)+2x+1-(151)=0

We add all the numbers together, and all the variables

2x-5(4x-2)-150=0

We multiply parentheses

2x-20x+10-150=0

We add all the numbers together, and all the variables

-18x-140=0

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

-18x=140

x=140/-18

x=-7+7/9
