Question

2m+5=5(m-7)-3m equals??

Answer 1

2m + 5 = 5(m - 7) - 3m

2m + 5 = 5m - 35 - 3m

2m + 5 = 2m - 35

2m + 5 - 5 = 2m - 35 - 5

2m = 2m - 30

2m - 2m = 2m - 2m - 30

0 = -30

0 does not equal -30 - so this is an inequality - cannot solve for m

No solution

Answer 2

2m+5=5(m-7)-3m
first, use distributive property...
2m+5=5m-35-3m
next, combine like terms on the right side...
2m+5=2m-35
next, subtract 2m from both sides.
2m+5=2m-35
-2m   -2m
you will get....
5=-35 in which is not true. This means the equation has no solution.
