Answer: (1, -5)
Step-by-step explanation:
I got you...
In solving system of equations there are three ways..
lets use addition
First we need to cancel out one of the variables
Lets cancel out the y
In order to do this lets multiply the top equation by -2 to get 2y and 4y to cancel out.
(-2)(-9x+2y) = -19(-2)
18x - 4y = 38
Now our system looks like this:
18x - 4y = 38
5x + 4y = -15
lets add these together
18x - 4y = 38
5x + 4y = -15 +
= 23x = 23
x = 1
We know x = 1, so substitude 1 for x in one of the equations
5(1) + 4y = -15
5 + 4y = -15
4y = -20
y = -5
This is the y value
Our final answer is (1, -5)
As an ordered pair
