Solve Equations 1
5h + 2 + 2h = 23
h = 3
2(x + 5) = 14
x = 2
Solve. 8b + 3b = 121
b = 11
4x + 1 = 13
x = 3
2x = -18
x = -9
3b + b - 8 = 4
b = 3
5(d - 2) = 40
d = 10
Solve. 19x - 24x = -25
x = 5

The sum of 3 consecutive integers is -57. What are the integers?
-20, -19, -18
3a + 12 - 6a = -9
a = 7
7(4 - t) = -84
t = 16
Simplify. 3 + 5(a + 4)
5a + 23
7 = -3x - 2
x = -3
3(x + 4) - 2(3x - 2) = 1
x = 5
-6 = -3y + 4 + 5y
y = -5
-2(x - 9) = -24
x = 21
Simplify. - (2b - 4)
-2b + 4
-6(m + 1) + 18 = 24
m = -2
