Solve for x:
13 − 4x = 1 − x

Definition

Answer with work:
13-4x = 1-x
13 = 1 +3x
12= 3x
x = 4

Term

Solve for x:
−10 + x + 4 − 5 = 7x − 5

Definition

Answer with work:
−10 + x + 4 − 5 = 7x − 5
-11 + x = 7x - 5
-11 = 6x - 5
-6 = 6x
x = 1

Term

Solve for x:
5 + 2x = 2x + 6

Definition

Answer with work:
5 + 2x = 2x + 6
2x = 2x + 1
No solution.
When you subtract 2x from 2x you get zero, so there are no x's left.

Term

Solve:
2x + 3 = 2x + 3

Definition

Answer with work:
