Solve for X: 2=3x+20

A) - 2

B) - 3

C) - 5

D) - 6

Answer: D (-6)

reasoning: 2 - 20 = 3x

-18 = 3x

-18/3 = x

-6 = x

Answer: x = - 6

Step-by-step explanation: To solve for x, we first isolate the term containing x which in this problem is 3x. Since 20 is being added to 3x, we subtract 20 from both sides of the equation.

On the left, 2 - 20 is - 18 and on the right, the + 20 and - 20 cancel out.

So we have - 18 = 3x.

Since x is being multiplied by 3, we can finish things off by dividing both sides of the equation by 3.

On the right the 3's cancel and on the left, - 18 divided by 3 is - 6.

So x = - 6 is the solution to this equation.
