Question 362367
-3x-y=-10...................1
4x-4y=8.....................2
multiply equation 1 by-4
12x+4y=40
add it to 2
16x=48
x=3
plug value of x in 1
-9-y=-10
y=1
(3,1) is the solution
...
if you need to solve by graphing then generate 3 values of y for various values of x for both equations Example
1. (1, 7) (2 ,4)
2.(1-1)

{{{graph(300,300,-5,12,-5,5,(-3x+10),(x-2))}}}
