If (2x + 3y) = 8, and (x + 2y) = 5 then find x and y--​

Answer 1

Answer:

By elimination method

Step-by-step explanation:

2x+3y=8. __(1)

x+2y=5. ___(2)

multiply equation (2) by 2

2×(x+2y)=2×5

2x+4y=10. ____(3)

subtract equation (1) from (3)

2x+4y=10

- 2x+3y=8

_________

0x+y=2

y=2

putting the value of y in equation (1)

2x+3y=8

2x+3(2)=8

2x+6=8

2x=8-6

2x=2

x=2/2

x=1

therefore,x=1 and y=2
