(In this problem, n/mx means [tex]\frac{n}{m}x[/tex]
y - x = 2
y = 2 + x
Substitute this into the other equation.
2 + x = -1/4x + 7
Convert all x to mixed numbers.
2 + 4/4x = -1/4x + 7
Bring x's to one side, and other terms to the other side.
5/4x = 5
Multiply by 4 to cancel the fraction
5x = 20
Divide by 5.
x = 4
Substitute into an equation.
y = -1/4(4) + 7
y = -1 + 7
y = 6
The point when you apply substitution is (4, 6)
