Question

1. $\frac{-3 + 3(-13 + m)}{3}$

-1 + - 13 + m
+13 +13
m = 12

1. $\frac{p}{27}-10=-11$
2. $-9=\frac{b}{3}-2$

Explanation:

Step1: Solve the equation $\frac{p}{27}-10=-11$

Add 10 to both sides.
$\frac{p}{27}-10 + 10=-11 + 10$
$\frac{p}{27}=-1$

Step2: Isolate $p$

Multiply both sides by 27.
$\frac{p}{27}\times27=-1\times27$
$p = - 27$

Step3: Solve the equation $-9=\frac{b}{3}-2$

Add 2 to both sides.
$-9 + 2=\frac{b}{3}-2+2$
$-7=\frac{b}{3}$

Step4: Isolate $b$

Multiply both sides by 3.
$-7\times3=\frac{b}{3}\times3$
$b=-21$

Answer:

$p=-27$, $b = - 21$
