hope it helps u mark me as brainlist follow me like my all answers

Answer 2

Answer:

$x + 7 = 9 \\ x = 7 - 9 \\ x = - 2 \\ \\ \frac{x}{4} = 25 \\ x = - 4 \times 25 \\ x = - 100 \\ \\ 9y = - 135 \\ y = \frac{9}{135} = - 15 \\ y = - 15 \\ \\ 3(x - 3) = 15 \\ 3x + 3 = 15 \\ x = - 15 - 3 - x \\ x = - 8 \\ \\ 7y + 3 = 9 \\ y = \frac{ - 7}{3} = 9 \\ y = 3 - 9 = - 6 \\ y = \frac{ - 6}{7}$

I hope it help you........
