3. 4(4m - 3)-(m - 5)=-52

Explanation:

Step1: Expand the expressions

$4\times(4m - 3)-(m - 5)=16m-12 - m + 5$

Step2: Combine like - terms

$16m-12 - m + 5=(16m - m)+(-12 + 5)=15m-7$

Step3: Solve the resulting equation

$15m-7=-52$. Add 7 to both sides: $15m=-52 + 7=-45$. Then divide both sides by 15: $m=\frac{-45}{15}=-3$

Answer:

$m=-3$
