Question

8. Find the solutionof the equation x - y=2 and x + y=4​

Answer 1

Answer:If x=a,y=b is the solution of the equations x-y=2 and x+y =4, then find the values of a and b Get the

Given, x=a and y=b.Given equations, x-y=2( assume it as equation 1) x+y=4( assume it as

Step-by-step explanation:

Answer 2

Answer:

x=3, y=1

Step-by-step explanation:

x=A

y=B

x-y=2

x+y=4

A-B=2

A+B=4

cross multiply

4(x-y)=2(x+y)

4x-4y=2x+2y

2x=6y

x=3y

x=3, y=1
