Solve for X.

x + 4 = - 15

Answer: x = - 19

Step-by-step explanation: When you're asked to solve for x in an equation, what you're really being asked to do is get x by itself on one side of the equation.

In this problem since 4 is being added to x, in order to get x by itself, we must subtract 4 from the left side of the equation and when we subtract 4 from the left side of the equation, remember that we must also subtract 4 from the right side of the equation.

So on the left, + 4 and - 4 cancels out and on

the right, - 15 - 4 simplifies to - 19.

So x = - 19.

x = - 19

Step-by-step explanation:

1. subtract 4 from both sides

-15 - 4 = - 19
