3x-2y = -5
4x+3y = -18
- - - - -
12x-8y = -20
12x+9y = -54
Now you just have to subtract normally.
12x - 8y = -20
-
12x + 9y = -54
-------------
0 -17y = 34
y = -2
From there, you can find the X
3x-2y=-5 and 4x+3y=-18
i need to graph and find the intersection
3 answers
What?? im so confused i need to find the intersection like a point on a graph
y= -2 is one part of the point on the graph
4x+3y = -18
4x+3(-2) = -18
4x -6 = -18
4x = -12
x = 3
The intersection point would be (3,-2)
4x+3y = -18
4x+3(-2) = -18
4x -6 = -18
4x = -12
x = 3
The intersection point would be (3,-2)
