Its only one math question show right steps then get brainliest and right answer ofc
valkas [14]

Step-by-step explanation:

equation.

2(m+10)=4(m−15)

(2)(m)+(2)(10)=(4)(m)+(4)(−15)(Distribute)

2m+20=4m+−60

2m+20=4m−60

Step 2: Subtract 4m from both sides.

2m+20−4m=4m−60−4m

−2m+20=−60

Step 3: Subtract 20 from both sides.

−2m+20−20=−60−20

−2m=−80

Step 4: Divide both sides by -2.

−2m−/2=−80/−2

m=40
