Question

4x + 10 = 2x - 14
Find the value of x.

Answer 1

Answer:

x= -12

Step-by-step explanation:

Simplifying

4x + 10 = 2x + -14

Reorder the terms:

10 + 4x = 2x + -14

Reorder the terms:

10 + 4x = -14 + 2x

Solving

10 + 4x = -14 + 2x

Solving for variable 'x'.

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

Add '-2x' to each side of the equation.

10 + 4x + -2x = -14 + 2x + -2x

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

10 + 2x = -14 + 2x + -2x

Combine like terms: 2x + -2x = 0

10 + 2x = -14 + 0

10 + 2x = -14

Add '-10' to each side of the equation.

10 + -10 + 2x = -14 + -10

Combine like terms: 10 + -10 = 0

0 + 2x = -14 + -10

2x = -14 + -10

Combine like terms: -14 + -10 = -24

2x = -24

Divide each side by '2'.

x = -12

Simplifying

x = -12

Step-by-step explanation:

Step 1: Define

Identify

4x + 10 = 2x - 14

Step 2: Solve for x

1. [Subtraction Property of Equality] Subtract 2x on both sides:                      2x + 10 = -14
2. [Subtraction Property of Equality] Subtract 10 on both sides:                       2x = -24
3. [Division Property of Equality] Divide 2 on both sides:                                  x = -12
