You can put this solution on YOUR website! 3(m-2)+4-m=18 :given
.
Multiply the first term to remove the parentheses...
3m -6 +4 -m = 18
.
Collect terms
2m - 2 = 18
.
Add 2 to both sides
2m = 20
.
Divide both sides by 2
m = 10
.
Check by substituting back into the original equation.
.
3(m-2)+4-m=18
3(10-2)+4-10=??
3(8) +4 -10 = 24 + 4 -10 = 18 :TRUE:
.
m = 10 is the answer.
