Question

find x+3y=15;2x+2y=10 using elimination method​

Answer 1

Step-by-step explanation:

the value of x=0 and the value of y=5

Answer 2

Answer:

y=5 , x= 0

Step-by-step explanation:

x+3y = 15 -(1)

2x+2y=10-(2)

from (1) we obtain :

x=15-3y ‐(3)

putting x in (2)

2(15-3y)+2y=10

30-6y +2y=10

-4y =10-30

y= -20/-4

y=5

putting y in (3) ,

x=15-3×5

x=0
