Given: 3x + y = 1.

Solve for y.

y = -3 x - 1
y = -3 x + 1
y = 3 x - 1

y = -3x + 1

Explanation:

Isolate the variable, y. Note the equal sign, what you do to one side, you do to the other. Subtract 3x from both sides of the equation:

3x + y = 1

3x (-3x) + y = 1 (-3x)

y = -3x + 1

y = -3x + 1 is your answer.
