Question

x+y=5;x-y=3
solve the following simultaneous problems ​

Answer 1

Answer:

Mark me as brainliest

X=4, Y=1

Step-by-step explanation:

x+y= 5--------(1)

x-y= 3---------(2)

From (1)

x+y=5

x=5-y------------(3)

$ubstitute (3) in (2)

x-y= 3

(5-y)-y =3 from-(1)

5-2y = 3

-2y= 3-5

-( -2y= -2)

2y = 2

y=1

$ubstitute y=1 in equ--(1)

x+y= 5

x+1= 5

x = 5-1

x =4

.°. X=4, Y=1
