9x plus 5y equals 3550?
To solve for two unknown variables (x and y) you require two independent equations,
A system of linear equations with an infinite number of solutions?
This can happen in different ways: a) More variables than equations. For instance, a single equation with two variables (such as x + y = 15), two equations with three variables, two equations with four variables, etc. b) To of the equations describe the same line, plane, or hyper-plane - this, in turn, will result in that you "really" have less equations than it seems. For example: y = 2x + 3 2y = 4x + 6 The second equation is simply the first equation multiplied by 2.

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.
How do you solve the equation x-7y equals 3?
One linear equation in two variables cannot be solved. You can only express one of the variables in terms of the other.
