Question

If 3x + 10 = 10 + 2x, what is the value of x?

A) x = 4
B) x = -4
C) x = -1
D) x = 0

Answer 1

x=0

Explanation:

3x + 10 = 10 + 2x

Subtract 2x from each side

3x-2x + 10 = 10 + 2x-2x

x+10 = 10

Subtract 10 from each side

x+10-10 = 10-10

x=0

Answer 2

x=0

Explanation:

3x + 10 = 10 + 2x

Subtract 2x from each side

3x-2x + 10 = 10 + 2x-2x

x+10 = 10

Subtract 10 from each side

x+10-10 = 10-10

x=0
