Jenny biked 3 miles less than twice the number of miles Marcus biked. Jenny biked a total of 4 miles. Write an equation to determine how many miles Marcus biked.

3 + 2x = 4
4 = 2x − 3
x − 4 = 2(3)
x over four = 2(3)

1 answer

Let x be the number of miles Marcus biked.

2x - 3 = 4

The equation to determine how many miles Marcus biked is 2x - 3 = 4.
