Question

2x-3y=4
-2x+y=5


Using the elimination method, solve this system of equations

Answer 1

Answer:

both 2x is cancelled

Step-by-step explanation:

3y = 4+5

3y=9

y= 9/3

y=3

put value of y in equation1

2x-3 into 3=4

2x-9=4

2x= 4+9

2x=13

x= 13/2

ok

Answer 2

Answer:

x+y=5

2x-3y=4

or multiplying by 3 in equ 1

now adding eq 3 and 2

3x+3y=15

2x-3y=4

5x=19

x=19/5

putting value of x in equ 1

19/5+y=5

y=25-19

y=6
