Review the steps for solving the system. –3x – 5y = 1 − 1 7 x − 5 7 y = 3 1. Multiply the second equation by 7 to get x + 5y = 21. 2. Add the equations together to get –2x = 22. 3. Solve for x to find x = –11. 4. Substitute x into an equation to find y = 32 5 . In which step was an error made? In step 1, the multiplier should be –7. In step 2, the x-variable should be eliminated when the equations are added together. In step 3, both sides of the equation should be multiplied by –2 rather than divided by –2. In step 4, substituting x = –11 into the first equation does not yield a value of StartFraction 32 Over 5 EndFractionfor y.
