Lyle was a careful craftsman, but he wasn't very
creative. For example, he only sold two types of
wooden benches: stained and unstained. The un-
stained benches cost $20 each, and the stained
cost $32 each. If Lyle sold 21 benches last month
(stained and unstained combined) and collected a
total of $600, how many unstained benches did he
sell?

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x
