100

110

180

120

90

Answer 1

Resposta:

Let's solve your equation step-by-step.

m+420=3m+240

Step 1: Subtract 3m from both sides.

m+420−3m=3m+240−3m

−2m+420=240

Step 2: Subtract 420 from both sides.

−2m+420−420=240−420

−2m=−180

Step 3: Divide both sides by -2.

−2m/−2=−180/−2

m=90

Explicação passo a passo:

Answer 2

$m + 420 = 3m + 240 \\ m - 3m = 240 - 420 \\ - 2m = - 180 \\ 2m = 180 \\ m = \frac{180}{2} \\ m = 90 \\ option \: e.$
