Question:

Using the following equation, solve for x and state how many solutions the equation has. -7x + 5 = 2x + 8 -9x

Answer:

Step 1- Combine like terms: -7x + 5 = -7x + 8 Step 2- Get the variable on one side of the equal sign by adding 7x to both sides: (7x)+ -7x + 5 = -7x + 8 + (7x) 5 = 8 Since the variable was eliminated on both sides, we are left with 5 = 8. Since 5 can never equal 8, that tells us there are no solutions to this equation.
