Question

titution method:
(i) 2x + y = 5
3x + 2y = 8​

Answer 1

Step-by-step explanation:

2x=5-y

3(5-y)+2y=8

15-3y+2y=8

Y=7

X=1

Answer 2

Step-by-step explanation:

there are two equations ;

2x+y=5. (1)

3x+2y=8. (2)

from equation (1)

y=5-2x. (3)

put it in (2) equation

3x+2(5-2x)=8

3x+10-4x=8

-x=8-10

-x=-2

x=2

put it in (3)equation

y=5-2(2)

y=5-4

y=1
