y = 5
A pencil costs $2. How many pencils can you buy with $10?
2x=10
x=5
x−(−4)=10
x = 6
x / 6 = 3
x = 18
2y + 4 = -2
y = -3
A movie ticket costs $8, and popcorn costs $5. If you spent $29 total, how many tickets did you buy?
8x+5=29
x = 3
a - 4 = -2
a = 2
y/ -4 = 9
y = -36
3x / 2 + 5 = 11
x = 4
Ben runs 2 km more than twice the distance Alice runs. If Ben ran 18 km, how far did Alice run?
2x+2=18
x = 8
4 - y = -12
y = 8
