Put the equation in standard form with a positive X coefficient y + 3 = 3 (x+5)

3x - y = - 12

Step-by-step explanation:

The equation of a line in standard form is

Ax + By = C (A is a positive integer and B, C are integers)

given

y + 3 = 3 (x + 5) ← distribute

y + 3 = 3x + 15 (subtract y from both sides)

3 = 3x - y + 15 (subtract 15 from both sides)

- 12 = 3x - y, thus

3x - y = - 12 ← in standard form

3x + y = - 12.

Step-by-step explanation:

y + 3 = 3 (x+5)

y + 3 = 3x + 15

3x + 15 = y + 3

3x - y + 15 = 3

3x + y = - 12
