What is the answer to 2(3x-4)-5=-7
kozerog [31]

Answer: x = 1

Step-by-step explanation:

1) Reorder the terms:

2(-4 + 3x) + -5 = -7

(-4 * 2 + 3x * 2) + -5 = -7

(-8 + 6x) + -5 = -7

2) Reorder the terms:

-8 + -5 + 6x = -7

3) Combine like terms: -8 + -5 = -13

-13 + 6x = -7

4) Solving

-13 + 6x = -7

5) Solving for variable 'x'.

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

7) Add '13' to each side of the equation.

-13 + 13 + 6x = -7 + 13

8) Combine like terms: -13 + 13 = 0

0 + 6x = -7 + 13

6x = -7 + 13

9) Combine like terms: -7 + 13 = 6

6x = 6

10) Divide each side by '6'.

x = 1

11) Simplifying

x = 1
