# Create an Equation with a Given Solution

Directions: Using the digits 0 to 9 at most one time each, fill in the boxes to write three equations whose solution is -1/2.

### Hint

What does it mean to be a solution of the equation?
How would you check if a value is a solution to an equation?
What kind of numbers would you put in for the coefficients of x?

There are many arrangements. Here is one set.
2x + 5 = 4x + 6
2x + 7 = 4x + 8
8x + 5 = 4x + 3
