Solving with Combining Like Terms

100

7h + 2 = 23

h = 3

200

3b + b - 8 = 4

b = 3

300

3a + 12 - 6a = -9

a = 7

400

-6 = -3y + 4 + 5y

y = -5

Solving with Using the Distributive Property

100

2(x + 5) = 14

x = 2

200

5(d - 2) = 40

d = 10

300

7(4 - t) = -84

t = 16

400

-2(x - 9) = -24

x = 21

Equation Grab Bag

100

4x + 9 = 33

x = 6

200

x + 3x = -8

x = -2

300

4(y - 2) + y = -13

y = -1

400

-6(m + 1) + 18 = 24

m = -2

Special Cases

100

3x + 1 = 3x - 1

No solution because 1 does not equal -1

200

4x + x + 2 = 5x + 2 

Infinite because 0=0

300

3m - 2 = 7 - 6m

1 solution because m=1
