Question

Solve for x.
4x -9 = 2x +5

Answer 1

hence the required value of x is 7.

Answer 2

x = 7

Explanation:

Solve for x.

4x - 9 = 2x + 5

4x - 2x = 5 + 9

2x = 14

x = 14 : 2

x = 7

-----------------

check (replace "x" with "7")

4 * 7 - 9 = 2 * 7 + 5 (remember PEMDAS)

28 - 9 = 14 + 5

19 = 19

the answer is good
