# How do you find the solution of the system of equations #5x - 2y = 4 # and #3x + y = 9 #?

##### 1 Answer

Find the value of one variable, and use that to solve for the other: See below.

#### Explanation:

A system of equations can technically be solve via one of 2 methods: elimination (I won't explain that here, since it is impractical, and I don't know that one too well; it makes your life necessarily difficult); substitution, where you isolate one of the variables in either equation (let's say you isolate

I'll demonstrate below:

*Substitution (personal recommendation)*

Step 1: Isolate **one variable** in **one** of the equations

Now replace

And solve for

Hope that helps!
