Select the first and second equations to eliminate the z variable (multiply the second equation by (1 and add). Notice in this case, the result was an equation in terms of just one variable (instead of two). Although this solves for y, you still need to repeat the process to find x.

is one in which the variables are to the first power; ax + b = c (a, b, c are constants) Examples are 2x - 5 = 4 and 3x + 5y = 12. When you are asked to solve a linear equation you are being asked to find the value of the variable which will make the equation a true statement. Example: x = 4 is the solution to the equation 2x - 4 = 4.

Packet 20: Solving Fractional Equations. Example: Step 1: Find the least common denominator. The least common denominator is _____ Step 2: Multiply every term in the equation by the least common denominator. Step 3: Reduce each term to create a “denominator free” equation. Step 4: Solve for the variable using the steps to solve an equation
