Hey there!

9x - 3 = 7(x + 3) + 2n

➡️ 9x - 3 = 7(x) + 7(3) + 2n

➡️ 9x - 3 = 7x + 21 + 2n

ADD -7x to BOTH SIDES

2n + 7x + 21 + (-7x) = 9x - 3 + (-7x)

SIMPLIFY IT!

2n + 21 = 2x - 3

ADD -21 to BOTH SIDES

2n + 21 + (-21) = 2x - 3 + (-21)

SIMPLIFY THIS AS WELL!

2n = 2x - 24

DIVIDE 2 to BOTH SIDES

2n/2 = (2x - 24)/2

FINALLY SIMPLIFY THIS LAST STEP!

n = x - 12

Answer: n = x - 12

Good luck on your assignment and enjoy your day!
