Question

if x+y=5, x-y=1(without solving write the number of solution of the given equation​

Answer 1

Answer:

x+y=5 changed to x=5-y

Also, x-y=1 changed to x=1+y

It just moves to right side, so you have to change the symbol in opposite before which number or something you moved.

After that, you can find x=5-y, x=1+y

Now, you can put them together.

It looks like this: 5-y= 1+y ; 5–1=y+y; 4=2y; y=2

Waiting!! Don’t forget the X!!

As you know, x=5-y, x= 1+y; just choose anyone put y into the equation.

x=5–2= 3

So that, the answer is x=3, y=2.

Hope it’s help.
