Question

4x+y+1 = 0
3x+2y = 3​

Answer 1

Answer:

4x+y=-1

3x+2y=3

3(4x+y=-1)

4(x+2y=3)

12x+3y=-3 ---- equation 1

12x+8y=12 --- equation 2

12x+3y=-3

12x+8y=12

- - = -

5y = -15

y= -15/5

y = -3

if y = -3 then x =

12x+8y=12

12x+8×-3 =12

12x+(-24) =12

12x= 12+24

12x= 36

x= 36/12

x= 3

x= 3 and y= -3
