This week's problem comes from the equation category.

How would you solve the equation $$4(3-m)-m=7$$?

Let's begin!

$4(3-m)-m=7$

 1 Expand.$12-4m-m=7$2 Simplify  $$12-4m-m$$  to  $$12-5m$$.$12-5m=7$3 Subtract $$12$$ from both sides.$-5m=7-12$4 Simplify  $$7-12$$  to  $$-5$$.$-5m=-5$5 Divide both sides by $$-5$$.$m=1$Donem=1
