TROLL ANSWER WILL GET REPORTED

m=10

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

−7(2m−6)+21=−77

(−7)(2m)+(−7)(−6)+21=−77(Distribute)

−14m+42+21=−77

(−14m)+(42+21)=−77(Combine Like Terms)

−14m+63=−77

−14m+63=−77

Step 2: Subtract 63 from both sides.

−14m+63−63=−77−63

−14m=−140

Step 3: Divide both sides by -14.

-14m/-14=-140/-14

m=10

m =10

Step-by-step explanation:

-14m+42+21=-77

-14m+63= -77

-14m= - 140

m=10
