Question 458794: how do you find the y-coordinate of the point of intersection for the two lines below?
-6x+7y=20
2x-3y=4
how do you find the x-coordinate of the point of intersection for the two lines below?
x-2y=-2
y=-6x+40 Answer by amoresroy(361) (Show Source):
You can put this solution on YOUR website! how do you find the y-coordinate of the point of intersection for the two lines below?
-6x+7y=20
2x-3y=4
Multiply the 2nd equation by 3 to get
6x-9y=12
Add the 2 equations to eliminate x
7y-9y=32
-2y = 32
y = -16
The y-coordinate is -16
----------------------------------------------
how do you find the x-coordinate of the point of intersection for the two lines below?
x-2y=-2
y=-6x+40
Rearrange 2nd equation to get
6x+y=40
Multiply the 1st equation by 6 to get
6x-12y=-12
Subtract above equation from 2nd equation
(6x-6x)+(y- -12y) = 40 - -12
13y = 52
y = 4
Substitute y =4 in 1st equation to solve for x
x-2(4) = -2
x = 6
The x-coordinate of the point of intersection for the two lines is 6.
