Question

Solve the following equations:x + y= 30 , x− y= 16​

Answer 1

Step-by-step explanation:

x+y=30 ___1

x-y=16___2adding eq 1 and 2

2x =46

x=23

sub x = 23 in eq 1

23+y =30

y = 30 - 23

y = 7

Answer 2

Step-by-step explanation:

x + y= 30.-----(1)

x− y= 16.------(2)

add (1) n (2)

2x= 46

therefore,x=23-------(3)

substituting (3) in (1)

therefore,y = 7
