Review the steps for solving the system. β3x β 5y = 1 β 1 7 x β 5 7 y = 3 1. Multiply the second equation by 7 to get x + 5y = 21. 2. Add the equations together to get β2x = 22. 3. Solve for x to find x = β11. 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 β7. 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 β2 rather than divided by β2. In step 4, substituting x = β11 into the first equation does not yield a value of StartFraction 32 Over 5 EndFractionfor y.
