Answer :
multiply the first equation by -2 to give
4x - 2y = 6
-x + 2y = 3 Adding:-
3x = 9
x = 3
Plug x = 3 into second equation:-
-3 + 2y = 3
2y = 6
y = 3
Answer is x=3, y = 3
4x - 2y = 6
-x + 2y = 3 Adding:-
3x = 9
x = 3
Plug x = 3 into second equation:-
-3 + 2y = 3
2y = 6
y = 3
Answer is x=3, y = 3
The solution of equations -2x+y=-3 and -x+2y=3 is x=3 and y=3.
What is equation?
An equation is basically a relationship between two variables in equal to form.
How to solve an equation?
The equations which are given as:
-2x+y=-3
-x+2y=3
multiply equation 2 by 2 and subtract equation 2 from 1
-2x+y=-3
-2x+4y=6
-2x+y-(-2x+4y)=-3-6
-2x+y+2x-4y=-9
-3y=-9
y=3
Put the value of y in -2x+y=-3
-2x+3=-3
-2x=-6
x=3
Hence the value of x and y in equations are 3 and 3.
