Question

Find the solutions for the equations x+y=10 and x-y=2

Answer 1

$x + y + x - y = 10 + 2 \\ 2x = 12 \\ x = 6 \\ \\ x + y = 10 \\ 6 + y = 10 \\ y = 4$

Answer 2

Answer:

X + y = 10 ........(1)

X - y = 2.............(2)

Adding the eq (1) &(2)

X+y=10

X-y = 2

=2x=12

X=6

Putting the value in eq (1)

6+y =10

Y=10-6

Y = 4
