To determine if ( m = 7 ) is a solution to the equation ( 2m = 3m + 3 ), substitute ( m ) with 7:
[ 2(7) = 3(7) + 3 ] [ 14 = 21 + 3 ] [ 14 = 24 ]
Since this statement is false, ( m = 7 ) is not a solution to the equation.

2m = 3m = 3/2Therefore m = 1.5
1m = 100cm 2m = 200cm 3m = 300cm So: 200cm+300cm=500cm Or 2m + 3m=5m
3*3*2 = 18 cubic metres.
-2m + 7 = m - 2 +7 +2 = m +2m 9 = 3m 3m = 9 m = 9/3 = 3 to test: -2(3) + 7 = (3) - 2 -6 + 7 = 3 - 2 1 = 1
5×2×3=30m^3 30m^3 is the answer
