Question

Plz Help!!! I need help will give you thanks five-stars brainiest and a good comment

Answer 1

x+y=15 _____(1)

x-y=4 _____(2)

By solving equations 2, we get

x-y=4

X=4+y ______(3)

By putting equation 3 in equation 1, we get

x+y=15

(4+y)+y=15

4+2y=15

2y=15-4

2y=11

y=11/2

By putting this value of Y in equation 2, we get

x-y=4

$x - \frac{11}{2} = 4$

$\frac{2x - 11}{2} = 4$

2x-11=4×2

2x-11=8

2x=8+11

X=19/2

I hope this will help you friend.
