Answer 2

Question: 2x - 4 = x - 1

Answer Step - by - Step:

Simplifying
2x + -4 = x + -1

Reorder the terms:
-4 + 2x = x + -1

Reorder the terms:
-4 + 2x = -1 + x

Solving
-4 + 2x = -1 + x

Solving for variable 'x'.

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

Add '-1x' to each side of the equation.
-4 + 2x + -1x = -1 + x + -1x

Combine like terms: 2x + -1x = 1x
-4 + 1x = -1 + x + -1x

Combine like terms: x + -1x = 0
-4 + 1x = -1 + 0
-4 + 1x = -1

Add '4' to each side of the equation.
-4 + 4 + 1x = -1 + 4

Combine like terms: -4 + 4 = 0
0 + 1x = -1 + 4
1x = -1 + 4

Combine like terms: -1 + 4 = 3
1x = 3

Divide each side by '1'.
x = 3

Simplifying
x = 3
