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
review the steps for solving the system
-3x - 5y = 1
- -/- 2 - 3 - 4 = 3
multiply the second equation by 7 to get x + 5y = 21
add the equations together to get –2x+= 22.
solve for x to find x=-11.
substitute x into an equation to find y
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 2 for y.
