Question

X+2y+1=0 2x-3y-12=0
By elimination method

Answer 1

Answer:

hence x = 3 and y = -2

Step-by-step explanation:

X+2y+1=0 ×3

2x-3y-12=0 ×2

3x+6y+3=0

4x-6y-24=0

4x+3x-24+3=0

7x-21=0

7x=21

X=3

put x=3 in x+2y+1=0

3+2y+1=0

2y+4=0

2y=-4

y= -2

Answer 2

Step-by-step explanation:

Solve the simultaneous equations using the the methof of substitution 3x-6y=24 and 2x+y=1 Get the answers you need,
