Caylee Novak · Answer 1

Our steps below

Choose a variable to represent the unknown.

Write an equation.

Solve the equation.

Check the solution for reasonableness.

x = number of bases Elena stole

equation

2x - 3 = 15

Solve for x:

2x - 3 = 15

2x = 18

x = 9

now check

2 (9) - 3=15

18-3=15

15=15
