Question

What is the solution to the system of equations that contains −3x + y = 3 and 2x − y = −1?

last question..

Answer 1

these two are linear equations and can be solved by substitution method easily

Answer 2

from 1st eq.
-3x+y=3
y=3x+3 (we get the value of y) now put it in 2nd eq.
2x-y=-1
2x-(3x+3)=-1
2x-3x-3=-1
-x-3=-1
x=-3+1
x=-2 now we get x and for y put x's value in any one eq. take eq. 1:
-3x+y=3
-3(-2)+y=3
6+y=3
y=3-6
y=-3
Hence we get x=-2 and y=-3
