Step by step
The question
Question: is (1, 1) a solution of 5x − 2y = 3.
5x − 2y = 3
is (1, 1) a solution?
1 Read x and y
The first number is always x.
The second is y.
So x = 1 and y = 1.
(1, 1) → x = 1, y = 1
2 Put them in
Put x = 1 and y = 1 in.
5(1) − 2(1) =? 3
Work out each side.
5 − 2 =? 3
Is 3 equal to 3?
Yes.
True!
3 = 3 true
It is true.
So (1, 1) is a solution.
(1, 1) is a solution
Let's look back.
First: read x and y.
Last: put them in.
Answer
(1, 1) is a solution
