Question

3 + 2x = -6x +4

Isolate the variable term on one side:
3 + 8x = 4
Isolate the constant on the other side:
8x = 1
Solve for x

Answer 1

x = 1/8

Explanation:

To solve for "x", isolate it from the other numbers. When "moving" a number to the other side as "x", do the reverse operation to both sides.

3 + 2x = -6x +4

3 + 8x = 4 Added 6x to both sides, opposite of -6x

8x = 1 Subtracted 3 on both sides, opposite of +3

The steps given are correct.

To finish solving, "move" the 8 away from "x". Since they are multiplying, the reverse operation is dividing.

Divide both sides by 8.

8x = 1

8x/8 = 1/8 8 divided by 8 cancels out, leaving "x" alone.
