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
