Question

the solution for the linear equation 2x +3y =2 and x+y=2 by elimination method​

Answer 1

Answer:

mark me as brainlist

Step-by-step explanation:

2x+3y=2        ........(1)

x−2y=8         ........(2)

From (2) we have x=8+2y

Put x=8+2y in (1) we get

2(8+2y)+3y=2

⇒16+4y+3y=2

⇒7y=2−16=−14

⇒y=2−14=−7

Put y=−7 in x=8+2y we get

x=8+2×−7=8−14=−6

∴x=−6 and y=−7

hope it will help you

Answer 2

Answer:

x= 4 and y= -2

Step-by-step explanation:

2x + 3y =2

x +. y=2

now multiply equation 1 with 1 and equation 2 with 2

2x + 3y =2

2x +.2y=4

on subtraction

2x + 3y =2

2x +.2y=4

-. -. -

y= -2. and x=4
