Answer:

x = 6 \\ y = 20

Step-by-step explanation:

1. Add the equations. The y's cancel out.

+ 4x - y =  + 4 \\  - 3x + y =  + 2 \\  -  -  -  -  -  -  -  \\ x = 6

2. Embed x in either equation and find y.

4x - y = 4 \\ 4(6) - y = 4 \\ 24 - y = 4 \\ 20 - y = 0 \\ y = 20

2x-3y=9<br> Find slope-<br> x-intercept-<br> y-intercept-
Readme [11.4K]

get the equation in slope intercept form

2x-3y=9

subtract 2x from each side

-3y = -2x +9

divide by -3

y = 2/3 x -3

slope = 2/3

y intercept = -3

x intercept set y=0 and solve

0 = 2/3 x -3

add 3 to each side

3 = 2/3 x

multiply each side by 3/2

9/2 = x

the x intercept is 9/2 or  4 1/2
