Hey there!

4x - 9 = 15

ADD 9 to BOTH SIDES

4x - 9 + 9 = 15 + 9

CANCEL out: -9 + 9 because it gives you 0

KEEP: 15 + 9 because it help solve for the x-value.

NEW EQUATION: 4x = 15 + 9

SIMPLIFY IT!

4x = 24

DIVIDE 4 to BOTH SIDES

4x/4 = 24/4

CANCEL out: 4/4 because it gives you 1

KEEP: 24/4 because it gives you the answer of the x-value

NEW EQUATION: x = 24/4

SIMPLIFY IT!

x = 6

Therefore, your answer is: x = 6 (Option D.)

Good luck on your assignment and enjoy your day!
