Step by step
The question
Question: is (0, 3) a solution of 4x + y = 3.
4x + y = 3
is (0, 3) a solution?
1 Read x and y
The first number is always x.
The second is y.
So x = 0 and y = 3.
(0, 3) → x = 0, y = 3
Careful!
Do not swap them.
The first number in (0, 3) is x.
Careful: not x = 3, y = 0 ✗
2 Put them in
Put x = 0 and y = 3 in.
4(0) + 3 =? 3
Work out each side.
0 + 3 =? 3
Is 3 equal to 3?
Yes.
True!
3 = 3 true
It is true.
So (0, 3) is a solution.
(0, 3) is a solution
Let's look back.
First: read x and y.
Last: put them in.
Answer
(0, 3) is a solution
