How do you solve this system of equations: #2x + y = - 2 and 5x + 3y = - 8#?
x = 2
y = -6
The question is asking to solve for 2 unknowns using 2 equations.
Let's start by rearranging one of the equation. That will make it easier to substitute. You can start with either equation, but I find the first equation easier to rearrange:
and insert that into the second equation:
Now that we have found the value for x, we can substitute in the value for x in any one of the equation to find the value for y.
