How many solutions does 3x - 9 = 3 (x - 3)

Step-by-step explanation:

Simplifying

3x + -9 = 3(x + -3)

Reorder the terms:

-9 + 3x = 3(x + -3)

Reorder the terms:

-9 + 3x = 3(-3 + x)

-9 + 3x = (-3 * 3 + x * 3)

-9 + 3x = (-9 + 3x)

Add '9' to each side of the equation.

-9 + 9 + 3x = -9 + 9 + 3x

Combine like terms: -9 + 9 = 0

0 + 3x = -9 + 9 + 3x

3x = -9 + 9 + 3x

Combine like terms: -9 + 9 = 0

3x = 0 + 3x

3x = 3x

Add '-3x' to each side of the equation.

3x + -3x = 3x + -3x

Combine like terms: 3x + -3x = 0

0 = 3x + -3x

Combine like terms: 3x + -3x = 0

0 = 0
