What is the solution to<br><br> −(6m+8) =4(17−m)

Sedbober [7]

Answer:

$\boxed{m = -38}$

Step-by-step explanation:

$-(6m+8) =4(17-m)$

→ Expand brackets

$-6m-8=68-4m$

→ Add 8 to both sides to collect the whole numbers

$-6m = 76-4m$

→ Add -4m to both sides to collect the m terms

$-2m=76$

→ Divide both sides by -10 to isolate m

$m=-38$
