Question

If x=a and y=b are the solutions of pair of equation x-y= 5and x+y=3,find a and b

Answer 1

Answer:

Step-by-step explanation:

x-y=5

x+y= 3

add the equation 1 and 2

x-y=5

x+y=3

2x=8

x=$\frac{8}{2}$

x=4

put x = 4 in equation 2

4+y=3

y=3-4

y=-1

x=4 & y=-1

x=a & y=b

a=4 & b=-1
