Question

2x+3y=2; x-2y=8 substitution

​

Answer 1

Answer:

put x = 0 so 2(0)+ 3y=2

Step-by-step explanation:

0+ 3y =2. = 3y=2. y=3/2 and x=0. now x-2y=8. 0-2(3/2) =8

Answer 2

Please mark as brainliest if it was helpful!!! ;-)

Answer:

x = 4, y = -2

Step-by-step explanation:

2x + 3y = 2

x - 2y = 8 ⇒ x = 8 + 2y

Substituting x = 8 + 2y in 2x + 3y = 2,

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

16 + 4y + 3y = 2

7y = 2 - 16

7y = -14

y = -14/7

y = -2

x = 8 + 2y = 8 + 2 x -2

= 8 + (-4)

= 8 - 4

= 4

∴ x = 4 and y = -2
