How do you solve for x equals y plus 3?

Answer 1

The first, and often most important, step in solving any problem is to understand

what the question is. You're not there yet.

"x = y + 3" is an equation that describes a straight line on a graph. Every point on

the line is a solution of the equation, and there are a huge number of points on a line.

In fact, there are an infinite number of them.

Every solution is a pair of numbers ... one for 'x' and one for 'y' ... and if you put

them in place of 'x' and 'y' in the equation, you get a true statement.

You can find solutions very easily. Just pick any number for 'y', stick it in the equation

in place of 'y', and look and see what 'x' must be.
