5x = 25
X = 5
2x - 10 = 20
X = 15
2x + 5 = x + 1
X = -4
y - 3x = 12
y = 3x + 12
x - 10 = 100
x = 110
x - 12 = 20
x = 32
5x + 10x = 225
X = 15
-6h + 4 = -h + 9
y - 6 = 3x
y = 3x + 6
x/5 = 2
X= 10
x + 6 = 33
2(2x + 9) = 98
X = 20
6n - 12 = n + 3
N = 3
y + 12 = 2x
y = 2x - 12
4(x + 9) = 96
x = 15
x/5 = 20

Your long distance telephone provider offers two plans. Plan A has a monthly fee of $15 and $0.25 per minute. Plan B has a monthly fee of
$20 and $0.05 per minute. Write and solve an equation to find the number of minutes that you must talk to have the same cost for each of the plans.
15 + 0.25x = 20 + 0.05x
X = 25 minutes
x/12 = 9
X = 108
8(x + 9) = 112
X = 5
3(b - 4) = 5b - 2
b = -5
12 = x - y
One movie club charges a $100 membership fee and $10 for each movie. Another club charges no membership fee but movies cost $15 each. Write and solve an equation to find the number of movies you need to buy for the cost of each movie club to be the same.
