5x - 3y = -7
3x + 3y = -9
This is a system of equations, here we need to find the value of x and y.
There are several methods to find x and y.
-Elimination
-Substitution
-Equality
-Graphing
-Determinants
Finding y by elimination
5x - 3y = -7
3x + 3y = -9
8x = -16
8x = -16
x = -16/8
x = -2
Find y
5(2) - 3y = -7
10 - 3y = -7
-3y = -7 - 10
-3y = -17
y = 17/3
Result
x = -2 y = 17/3
