Solve for m.
4m - 12 = 2m + 4
m=8
Write the equation!
The some of three times a number and 12 is 24
3x + 12 = 24
4x^2 + 20 = 56
x = 3
-3/4 m = 18
m = -24
Solve for z. -2(z - 5) + 6z = 14
z = 1
-1/2 x + 3 < 9
x > -12

-15
-14
-13
-12
-13 and -12
Solve for b.
m/8 = -9
b = -72
Solve for g. 4 - (g + 7) = 3g - 13 - 4g
no solutions
(x + 4)/5 > 2
x > 6
