To solve the equation -4.5x + 27 = 45, follow these steps:
Start by isolating the variable term, which is -4.5x. To do this, subtract 27 from both sides of the equation:
-4.5x + 27 - 27 = 45 - 27
This simplifies to:
-4.5x = 18
Now, you want to solve for x. Divide both sides of the equation by -4.5 to isolate x:
(-4.5x) / (-4.5) = 18 / (-4.5)
This simplifies to:
x = -4
So, the solution to the equation -4.5x + 27 = 45 is x = -4.
