If 3m - 7 = 8, then m = 5

-8 + (5m - 6m) = -8 + (-m) = -8 - m

6m + 20 = 9m - 4 24 = 3m m = 8

40

It is the property that equals plus equals are equals.

If 3m - 7 = 8, then m = 5

-3m + 8 = 2 -3m = 2 - 8 -3m = -6 m = -6/-3 m = 2

simplified it equals, 9m+8

m = 8

5m = 40m = 40/5m = 8

-3m + 8 - 7 = -3m + 1

5m=40/5=/5m=8

-8 + (5m - 6m) = -8 + (-m) = -8 - m

It is: 9m +8 -4m +7 -5m = 15

5m = 7 + 4msubtract 4m from both sides1m = 7m = 7=================================Oops. That first solution lost the '8' from the left side.An attempt to check the given equation with "m=7" fails.Try it like this:5m + 8 = 7 + 4mSubtract 4m from each side:m + 8 = 7Subtract 8 from each side:m = -1

m = 12. 3 x 12 = 36, 36 + 8 = 44.
