3x + x + x + x - 3 - 2 = 7 + x + x In the equation above, what is the value of x? A) - 5 7 B) 1 C) 12 7 D) 3

x=3

Step-by-step explanation:

3x + x + x + x - 3 - 2 = 7 + x + x

Combine like terms

6x - 5 = 7+2x

subtract 2x from each side

6x-2x - 5 = 7+2x-2x

4x - 5 = 7

Add 5 to each side

4x-5 + 5 = 7+5

4x = 12

Divide by 4

4x/4 = 12/4

x=3
