Answer:

x = 1

Step-by-step explanation:

7x - 20 = 2x - 3(3x + 2)

7x - 20 = 2x - 9x - 6

7x - 2x + 9x = - 6 + 20

14x = 14

x = 14/14

x = 1

Answer:

7x-20=2x-3(3x+2)

We move all terms to the left:

7x-20-(2x-3(3x+2))=0

We calculate terms in parentheses: -(2x-3(3x+2)), so:

2x-3(3x+2)

We multiply parentheses

2x-9x-6

We add all the numbers together, and all the variables

-7x-6

Back to the equation:

-(-7x-6)

We get rid of parentheses

7x+7x+6-20=0

We add all the numbers together, and all the variables

14x-14=0

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

14x=14

x=14/14

x=1
