Question

2x – = 9, 3x + = 2. step by step

Answer 1

Answer:

Step-by-step explanation:

Simplifying

2x + 9 = 3x + 2

Reorder the terms:

9 + 2x = 3x + 2

Reorder the terms:

9 + 2x = 2 + 3x

Solving

9 + 2x = 2 + 3x

Solving for variable 'x'.

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

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

9 + 2x + -3x = 2 + 3x + -3x

Combine like terms: 2x + -3x = -1x

9 + -1x = 2 + 3x + -3x

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

9 + -1x = 2 + 0

9 + -1x = 2

Add '-9' to each side of the equation.

9 + -9 + -1x = 2 + -9

Combine like terms: 9 + -9 = 0

0 + -1x = 2 + -9

-1x = 2 + -9

Combine like terms: 2 + -9 = -7

-1x = -7

Divide each side by '-1'.

x = 7

Simplifying

x = 7
