Answer 1

Therefore, Eric earned $7

Explanation:

Robert earned $10, which was 4 less than twice what Eric earned. How much money did Eric earn?

Let the number of money Eric earned = x

So we have:

$10 = 2× x - 4

10 = 2x - 4

Collect like terms

2x = 10 + 4

2x = 14

Divide both sides by 2

x = 14/2

x = $7

Therefore, Eric earned $7
