Question

Find the value of x when 5x + 6 - 2x = 9.

Answer 1

`5x + 6 - 2x = 9 \\ 5x - 2x = 9 - 6 \\ 3x = 3 \\ x = (3)/(3) \\ \boxed{x = 1}`

x=1 is the right answer.

Answer 2

x=1

Explanation:

combine the like terms

5x + 6 - 2x = 9

3x+6=9

then subtract 6 on both sides

3x=3

lastly divide 3 on both sides

x=1
