Shane biked 1 mile less than three times the number of miles Lissette biked. Shane biked a total of 7 miles. Write an equation to determine how many miles Lissette biked.

Answer 1

sh=3L-1=7

3L=-1-sh

3L=8

L=8/3

Answer 2

Shane biked 1 mile less than three times the number of miles Lissette biked. Shane biked a total of 7 miles. Write an equation to determine how many miles Lissette biked.

1 mile less tells us to subtract.

3 times tells us to multiply

total means equal to.

So the equation to find Lissette's mils would be

7=3L-1 then solve for L

7+1=3L-1+1

8=3L

8/3 = 3L/3

2.67 miles = L

Answer 3

x = the number of miles Lissette biked

3x-1=7
