# How do you solve for x in #3x + y =7#?

To begin isolating x, use algebraic manipulation to begin moving everything to the opposite side as the x term.

Begin by moving the y term.

Next, divide both sides by 3

To solve for ( x ) in the equation ( 3x + y = 7 ), you need to isolate ( x ) on one side of the equation. First, subtract ( y ) from both sides to move it to the other side of the equation:

[ 3x = 7 - y ]

Then, divide both sides by 3:

[ x = \frac{7 - y}{3} ]

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
