Step by step

Question: is (3, 2) a solution of x + y = 5.

x + y = 5

is (3, 2) a solution?

The first number is always x.

The second is y.

So x = 3 and y = 2.

(3, 2) → x = 3, y = 2

Careful!

Do not swap them.

The first number in (3, 2) is x.

Careful: not x = 2, y = 3 ✗

Put x = 3 and y = 2 in.

3 + 2 =? 5

Work out each side.

Is 5 equal to 5?

Yes.

True!

5 = 5 true

It is true.

So (3, 2) is a solution.

(3, 2) is a solution

Let's look back.

First: read x and y.

Last: put them in.

Answer

(3, 2) is a solution

Try this one yourself, then check:

is (1, 1) a solution of x + y = 2

Show the answer

(1, 1) is a solution
