Variables on Both Sides of an Equation Period 4 Benchmark MA

Definition The meaning of Variables on both sides of the equation is having a variable on each side of an equation. To solve the Equation you have to find the value of the variable. The meaning of Variables on both sides of the equation is having a variable on each side of an equation. To solve the Equation you have to find the value of the variable.

Example An example of a variable being on both sides of an equation is 2x + 3 = 3x. An example of a variable being on both sides of an equation is 2x + 3 = 3x. If x = 3 then we can find the answer to the problem. If x = 3 then we can find the answer to the problem. 2 * 3 = = 9 3 * 3 =9 2 * 3 = = 9 3 * 3 =9

Problems to Solve 1) 3x + 4 = 5x x = ? 2) 15 / x = x - 2 x = ? 3) 21 / x = x * 2 + 1x = ? 4) 5x + 45 = x * 10 x = ? 5) 36 / x = x - 5 x = ? 6) 1x + 2 = x + 2 x = ? 7) 54 / x = x + 3 x = ?

Solutions to the Problems 1) x = 2 2) x = 5 3) x = 3 4) x = 9 5) x = 9 6) x = 2 7) x = 6
