Answer:
M=-8
Step-by-step explanation:
21+6m=3(m−1)
Step 1: Simplify both sides of the equation.
21+6m=3(m−1)
21+6m=(3)(m)+(3)(−1)(Distribute)
21+6m=3m+−3
6m+21=3m−3
Step 2: Subtract 3m from both sides.
6m+21−3m=3m−3−3m
3m+21=−3
Step 3: Subtract 21 from both sides.
3m+21−21=−3−21
3m=−24
Step 4: Divide both sides by 3.
3m/3=-24/3
M=-8
Answer:
m = - 8
Step-by-step explanation:
Given
21 + 6m = 3(m - 1) ← distribute
21 + 6m = 3m - 3 ( subtract 3m from both sides )
21 + 3m = - 3 ( subtract 21 from both sides )
3m = - 24 ( divide both sides by 3 )
m = - 8
