Question

Pls help need it ASAP
the answer is not x=3, y=3

Answer 1

x = 4 and y = 1

Explanation:

4x - y = 15

2x + y = 9

Isolate x --

4x - y = 15 (add y to both sides)

4x = 15 + y (divide both sides by 4)

`(4x)/(4) =(15)/(4) +(y)/(4)` (Simplify)

x =
`(15 + y)/(4)`

Substitute x = 15 + y/ 4 in the other equation

2 * 15 + y/ 4 + y = 9 (simplify)

15 + 3y/ 2 = 9 (simplify)

y = 1 and x = 4

HOPE THIS HELPS YA!!

Answer 2

x=4 and y=1

Explanation:

4x-y=15

2x+y=9

6x=24

x=24/6

x=4

4x-y=15

4(4)-y=15

16-y=15

-y=15-16

-y=-1 Divide both sides by -1

y=1
