Question

Write the equation in standard form 3x + 1 = 2y

1. 3x + 2y = 1

2. 3x - 2y = 1

3. 3x + 2y = -1

4. 3x - 2y = -1

Answer 1

The standard form of an equation is

`ax + by = c`

In the question, we have the following formula

`3x + 1 = 2y`

To get the formula in standard form, we first have to subtract 2y from both sides (since we need to get 2y on the left side)

`3x - 2y + 1 = 0`

Finally we subtract 1 from both sides (since we need the number on the right side)

`3x - 2y = - 1`

Hence, 4. is the correct answer.
