Concept Check
Circle the equation that is going to have a negative
solution.
Test Preparation
Circle the correct response.
What is the coefficient of x?
2x − 3 = 7

More Challenging
A tank sprung a leak and the water level started to
drop from 22 meters at a rate of 2 meters per hour.
Write and solve an equation to determine how long it
will take the water level to drop to 7 meters.
Mathematical Reasoning
A candle starts at 8 inches tall and burns 2 inches per
hour. Write and solve an equation to find the number of
hours (h) it was burning if it is currently 3 inch tall
22 meters
