To solve this we must first substitute x for 4 in 3x - 8
(3)(4) - 8

Now solve!
(3)(4) - 8
12 - 8
4

Your answer should be 4

M/n = p/q solve for p

mojhsa [17]

Answer:

$p=\frac{Mq}{n}$

Step-by-step explanation:

we have

$\frac{M}{n}=\frac{p}{q}$

Solve for p

That means ----> Isolate the variable p

Multiply by q both sides

$\frac{M}{n}(q)=\frac{p}{q}(q)$

Simplify right side

$\frac{M}{n}(q)=p$

Rewrite

$p=\frac{Mq}{n}$
