Answer:
f.
[tex]2(x + 6) \\ = 2x + 12 \\ \frac{2x = 12}{2} \\ x = 6[/tex]
g.
[tex]3k + 7 = 34 \\ 3k = 34 - 7 \\ \frac{3k = 27}{3} \\ k = 9[/tex]
H.
[tex]5(b + 28) = 150 \\ 5b + 140 = 150 \\ 5b = 150 - 140 \\ \frac{5b = 10}{5} \\ b = 2[/tex]
I.
[tex]9a + 7 \\ \frac{9a = 7}{9} \\ a = \frac{7}{9} [/tex]
J.
[tex]5y - 9 = 13 \\ 5y = 13 + 9 \\ \frac{5y = 22}{5} \\ y \frac{22}{5} [/tex]
