Question

M+7+(-15m) + 9-17m= 58

Answer 1

Answer:

$m=-\frac{42}{31}$

Step-by-step explanation:

$m+7+\left(-15m\right)+9-17m=58$

Remove brackets:

$m+7-15m+9-17m=58$

Group the similar terms together:

$m-15m-17m+7+9=58$

$-31m+16=58$

Subtract 16 from both sides:

$-31m+16-16=58-16$

$-31m=42$

Divide both sides by -31:

$\frac{-31m}{-31}=\frac{42}{-31}$

$m=-\frac{42}{31}$
