Solving the Equation: 1/2 - 3 + 6(x-3) = 5(8 - 0.4x)
In this article, we will solve the equation 1/2 - 3 + 6(x-3) = 5(8 - 0.4x). To do this, we will start by simplifying both sides of the equation and then solve for x.
Step 1: Simplify the Equation
Let's start by simplifying the left-hand side of the equation:
1/2 - 3 + 6(x-3)
= 1/2 - 3 + 6x - 18
= -17 + 6x
Now, let's simplify the right-hand side of the equation:
5(8 - 0.4x)
= 40 - 2x
Step 2: Equate the Two Expressions
Now that we have simplified both sides of the equation, we can equate them:
-17 + 6x = 40 - 2x
Step 3: Solve for x
To solve for x, we can add 17 to both sides of the equation:
-17 + 6x + 17 = 40 - 2x + 17
6x + 0 = 57 - 2x
Now, let's add 2x to both sides of the equation:
6x + 2x = 57
8x = 57
Finally, let's divide both sides of the equation by 8:
x = 57/8
x = 7.125
Therefore, the value of x is 7.125.
