Question

If x=a and y=b is a solution of the linear equations x-y=2 and x+y=4, then a and b will be
a) 1,2
b) 2,3
c) 1,3
d) 3,2

Answer 1

Step-by-step explanation:

Hope it helps to you all.

Answer 2

Answer:

the answer is c

Step-by-step explanation:

we are given the equation x-y = 2 , so if we further solve it , it will be x = 2+y .

now we are given one more equation , that is x+y = 4

so , since we now x = 2 + y , we substitute x value in x+ y = 4

so, 2 + y + y = 4

2 + 2y = 4

2y = 4-2

y = 2/2

y = 1

so we know the value ok y = 1

now we substitute y value in x = 2 + y to find x

x = 2 + 1

x = 3

so , hence y = 1 , x = 3
