True Equation: 3 + 4 = 7
False Equation: 2 x 6 = 12
Open Equation requiring two or more steps to solve: 5x + 2 = 17
Step 1: Subtract 2 from both sides of the equation:
5x + 2 - 2 = 17 - 2
5x = 15
Step 2: Divide both sides by 5 to solve for x:
5x/5 = 15/5
x = 3
Make up two equations, one that is true and one that is false. Create an example of an open equation that uses the variable x and would require two or more steps to solve.
