Question
Order the steps below to solve the system for x using the substitution method. y = x - 5x - 7y = -1
Solution
-
Start with the given system of equations: y = x - 5 x - 7y = -1
-
Solve the first equation for x: x = y + 5
-
Substitute (y + 5) for x in the second equation: (y + 5) - 7y = -1
-
Simplify the equation: -6y + 5 = -1
-
Subtract 5 from both sides: -6y = -6
-
Divide both sides by -6: y = 1
-
Substitute y = 1 into the first equation: 1 = x - 5
-
Add 5 to both sides: x = 6
So, the solution to the system of equations is x = 6, y = 1.
