In which step was an error made?
Review the steps for solving the system.
-3x - 5y=1
In step 1, the multiplier should be -7.
In step 2, the x-variable should be eliminated when
the equations are added together.
✓x
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.
O In step 3, both sides of the equation should be
multiplied by -2 rather than divided by-2.
O In step 4, substituting x = -11 into the first equation
does not yield a value of
4. Substitute x into an equation to find y =
for y
