If: y = 8/x and y = 7+x

Then: 8/x = 7+x

Multiply all terms by x: 8 = 7x+x^2 or x^2 +7x -8 = 0

Factorizing the above: (x-1)(x+8) = 0 => x =1 or x = -8

Through substitution contacts are made at: (-8, -1) and (1, 8)

How do you solve equations with fraction?

You solve equations with fractions the same way you solve other equations. You perform various arithmetic operations on both sides of the equals sign until you get the result you want.

You are given two equations which are both true and you are asked to solve for both x and y you plan to solve this set of equations by substituting part of one equation into the other so you end up wi?

Many equations can be plotted as a line or other curve in the x-y plane. If you have two equations and you plot the curve (or line) for each one. If the curves (or lines) intersect at one or more points, then the (x,y) coordinates for the intersection points will also be the x and y values which satisfy both equations to be true at the same time.
