Question

solve for x and y x-y=2 and x+y=4​

Answer 1

Answer:

x=3,y=1

Step-by-step explanation:

Our aim is to remove the y or x by adding or subtracting,

We can eliminate y by adding the two equations.

x-y+x+y=4+2

x+x-y+y=6

2x=6

x=6/2=3

x+y=4

We found that x is 3

y+3=4

y=1

You can also use trial and error method

Hope it helps

Answer 2

Let,

x-y=2---(1)

x+y=4---(2)

Then by adding eq(1) and eq(2),

2x=6

x=6/2

x=3

Now substitute value of x in eq(2)

3+y=4

y=4-3

y=1

Therefore, values of x is 3 and value of y is 1
