2 (x + 1) + 6 = 20 - 3x

multiply the bracket by 2

(2)(x)=2

(2)(1)=2

2x+2+6=20-3x

2x+8=20-3x

move 8 to the other side

sign changes from +8 to -8

2x+8-8=20-8-3x

2x=12-3x

move -3x to the other side

2x+3x=12-3x+3x

5x=12

divide both sides by 5 to get x by itself

5x/5=12/5

answer:

x=12/5

Answer:

x=2.4

Explanation:

2(x+1)+6=20-3x

We simplify the equation to the form, which is simple to understand

2(x+1)+6=20-3x

Reorder the terms in parentheses

+(+2x+2)+6=20-3x

Remove unnecessary parentheses

+2x+2+6=+20-3x

We move all terms containing x to the left and all other terms to the right.

+2x+3x=+20-2-6

We simplify left and right side of the equation.

+5x=+12

We divide both sides of the equation by 5 to get x.

x=2.4
