• If we now multiply the first equation by 2, we get the equivalent system 10 +2 =14 2 −2 =6 Adding these two equations results in the ’s canceling, leaving 12 =20, so =5 3. Plugging this back into the first equation (before we multiplied it by 2) gives 5(5 3)+ =7, or 25 3 + =7, so =7−25 3 =21 3 −25 3 =−4 3. The solution is (5 3

• Solving Equations Containing Fractions and Decimals page2.3-6 Example 3: Solve each equation by first clearing the fractions. a) x 3 + 1 = 5x 6 – 3 b) y 4 + 1 12 = y 3 – 1 6 Procedure: First identify the LCD, then multiply each side of the equation by the LCD to clear the fractions. Answer: a) x 3 + 1 = 5x 6 – 3 The LCD is 6.
(1)----> 2x + 3(1) = 5. 2x + 3 = 5. Subtract 3 from each side. 2x = 2. Divide each side by 2. x = 1. So, the values of x and y are 1 and 1 respectively. Problem 3 : Solve the system of equations using elimination method. Check the solution by graphing. 2x - 3y = 12. x + 3y = 6. Solution : 2x - 3y = 12 -----(1) x + 3y = 6 -----(2) Solving by Elimination. Solving 2 x 2 Systems of Equations; Freaky Things That Can Happen with 2x2's. Systems of Inequalities. EXERCISES.

If we now multiply the first equation by 2, we get the equivalent system 10 +2 =14 2 −2 =6 Adding these two equations results in the ’s canceling, leaving 12 =20, so =5 3. Plugging this back into the first equation (before we multiplied it by 2) gives 5(5 3)+ =7, or 25 3 + =7, so =7−25 3 =21 3 −25 3 =−4 3. The solution is (5 3 Solving by elimination. We have learned how to solve an equation when there is only one variable to consider. What happens if there are two? We will be able to solve for both "x" and "y" but only one at a time. We need to cancel out or eliminate a variable first.
How to solve a system of equations using elimination Elimination is a great way to solve real-life problems that involve more than one variable. Here's an example. Watch below.2 +3 =8 5 − =3 9) {2 + =8 −6 −3 =−20 10) {5 −3 =−14 3 +3 =10 11) {9 +6 =12 8 +3 =13 Directions: Write a system of equations for the situation.
