Answer» Answer: Here's what we know: E + s + y = 68 (their SCORES add up to 68) s = 2e (If Erik has half the points of Shee, then Shee has twice as MANY as Erik) y = s + 3 (Yael has three more points than Shee)
No to put the variable values in: e + 2e + s + 3 = 68 e + 2e + 2e + 3 = 68 Simplify: 5e + 3 = 68 Subtract 3 from both sides: 5e + 3 - 3 = 68 - 3 5e = 55 divide by 5: 5e / 5 = 55 / 5 e = 11 |
