Question

Solve: 2(3x + 1) =20

Answer 1

Simplifying

2(3x + -1) = 20

Reorder the terms:

2(-1 + 3x) = 20

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

(-2 + 6x) = 20

Solving

-2 + 6x = 20

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '2' to each side of the equation.

-2 + 2 + 6x = 20 + 2

Combine like terms: -2 + 2 = 0

0 + 6x = 20 + 2

6x = 20 + 2

Combine like terms: 20 + 2 = 22

6x = 22

Divide each side by '6'.

x = 3.666666667

Simplifying

x = 3.666666667

Answer 2

6x+2=20
6x=18
X=3
This is the answer
