Answer: X=-1/2 and y=5
Step-by-step explanation:
PE = m•g•h, where m is mass in kg, gis 9.8m/s2, and h is height above the earth in meters. If an object is on the ground, it's height above the earth is zero, so it has zero PE.

Step 1: Simplify each side, if needed.
Step 2: Use Add./Sub. Properties to move the variable term to one side and all other terms to the other side.
Step 3: Use Mult./Div. ...
Step 4: Check your answer.
I find this is the quickest and easiest way to approach linear equations.
Example 6: Solve for the variable.
