How do you solve 2=(5p-7)/4?

p=3

Explanation:

Multiply 4 on both sides to get rid of the denominator:

$4 \times 2 = \frac{5 p - 7}{\cancel{4}}$$\times \cancel{4}$

Add 7 to both sides to get the constant by itself:

$8 = 5 p - 7$
$+ 7 \textcolor{w h i t e}{a a a} + 7$

$15 = 5 p$

Divide both sides by 5 to find p:
$\frac{15}{5} = \frac{\cancel{5} p}{\cancel{5}}$

$3 = p$
