Question

Write an equation and solve. Show the equation, your work in solving the equation, and the solution in your answer. Manuel went shopping and bought 3 pairs of pants. He also spent five dollars on a pair of socks. When he got home, he realized that he had spent a total of seventy-one dollars. What was the cost of each pair of pants?

Answer 1

3x+5=71 is the equation

we have to subtract 5 to get rid of it on both sides:

3x=66

next, we divide 3 on both sides:

x=22

so, each pair of pants was $22
