Question

What is the solution of the system of equations?
4x-3y=15
2x+2y=4

Answer 1

4x-3y=15 equation 1
2x+2y=4. equation 2

multiplying equation 2 by 2

4x -3y=15
4x+4y=16

subtracting equation 2 from equation 1

-7y=7
y=-1
putting value of y in equation 1

4x -3(-1)=15
4x+3=15
4x=12
x=3

hope it helps you

Answer 2

4x-3y=15
3y=15-4x
y=(15-4x)/3
we have to put value 1 by 1
x=0 then y=5 like this many other solution will come

2x+2y=4
x=(4-2y)/2
then we again put value
y=0 then x=2 like this many other solution will come
