How to solve simple equation.

Determing like terms.

There are many ways to solve an equation of the form ax+b=c. A table of values of the expression ax+b may give a value that equals c. A graph of y=ax+b may reach the value c at a point whose x-cordinate can be determine. For example to solve 3x-46=17, you can make a table of values of 3x-46 for various values of x and check if 17 appears as value of y. You can graph y=3x-46 and check if it crosses the line y=17.

To find the opposite expression you have to know that -(-a) is a. For example -(15y+3)= -15-3.

Linear ineualities can be solved by finding equivalent inequalities in much the same way that equivalent quations can be found to solve linear equations. For exampole, -3x-46<17 is solved by adding 46 to each side and then dividing each side by -3 to get x>21. Notice when dividing or multiplying by a negative number, the inequality sign is reversed.
