m = 31m + 9 = 1(3) + 9 = 3 + 9 = 12

m = 20/9 or 2 and 2/9
-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
Given m equals 3 and n equals 1 then m3n3 equals?m3n3 = m*3*n*3 = 3*3*1*3 = [ 27 ]
If this is an algebra problem; m is a variable.therefore:3 * m = 9 (divide the right side by 3)m = 9/3 9/3= 3m = 3
"3m" means "3 times m", so if m=9, then: 3m = 3 x 9 = 27.
-4M+3=-9 -4M=-12 M=-12/-4 Negatives Cancel M=12/4 M=3

m=9/11 (nine-elevenths), or 0.8181818181...
m + 9 = 2 Therefore, m = 2 - 9 m = -7
4!
m/(-4) = 9m = 9 x (-4)m = -36
No! It equals 15, but 9-6=3.
2 - 3m + 7 = 4m - 9 - m - 28 46 = 6m 46/6 = 23/3 = 7.6666 = m
m=648
10/5 = M - 9-7 => M = 3 and 2/7 = 23/7
