12-38.

Write and solve an equation (or system of equations) for the situation below. Define your variable(s) and write your solution as a sentence.

Jessica has 147 coins that are all dimes and quarters. The number of quarters is 6 fewer than twice the number of dimes. What is the value of her coins? Homework Help ✎

Think of this situation as:

The number of dimes plus the number of quarters equals 147.

2 times the number of dimes minus 6 equals the number of quarters.

Define your variables:*x* = the number of dimes*y* = the number of quarters

Use steps 1 and 2 to build two equations. Then solve for *x* and *y*.

Remember to write your solution as a sentence, not just solve for the variables!
