Question

Solve for x and y
x-y=5 and x+y=1

Answer 1

Answer:

X = 3 and Y = -2

Step-by-step explanation:

By using substitution method:

X - Y = 5

=> X= 5 + Y -------- (i)

X + Y = 1 ----------(ii)

NOW,

BY PUTTING THE VALUE OF X IN EQUATION (ii),we get.

5 + Y + Y = 1

2Y = 1 - 5

Y = -4/2

Y = -2

AGAIN,

PUTTING THE VALUE OF Y IN EQUATION (i), WE GET.

X - (-2) = 5

X + 2 = 5

X = 5 - 2

X = 3.
