Simplify and Solve: First, we need to simplify and solve the first equation for m.3−2(9+2m)=mDistribute the −2 into the parentheses:3−18−4m=mCombine like terms:−15−4m=m
Combine Like Terms: Next, we add 4m to both sides of the equation to get all the m terms on one side:−15−4m+4m=m+4m−15=5m
Add and Divide: Now, we divide both sides by 5 to solve for m:−515=55mm=−3
