## Solving Linear Equations

Linear Equation: a mathematical expression that has an equal sign and linear expressions

Variable: a number that you don't know, often represented by "x" or "y" but any letter will do

Linear Expression: a mathematical statement that performs functions of addition, subtraction, multiplication, and division

x + 42x + 42x + 4y

x2(no exponents on variables)

2xy + 4(can't multiply two variables)

2x / 4y(can't divide two variables)

√x(no square root sign on variables)

Solve these linear equations by clicking and dragging a number to the "other" side of the equal sign. Remember that you are "isolating" the unknown "X" to solve the problem.
