2x-y=0 and 3x+2y=-14



help me tomorrow is my exam​

Answer 1

Answer:

X=2

y=4

Step-by-step explanation:

2x-y=0 __________(1)

3x+2y=-14__________(2)

multiple equation no 1 by 2

4x-2y=0 -----------------(3)

add both equation 3 &2

4x-2y=0

3x+2y=-14

----------------

7x=-14

X= ⁷/14

X=2

let substitute x=2 in eq 1

2x-y=0

2(2)-y=0

4 -y = 0

y=0+4

y=4
