x

Solution

To solve the equation:

4(6x4)=(4x6)+30-4(6x - 4) = -(4x - 6) + 30

Let's follow the steps to find xx.

Step 1: Expand both sides

First, expand both sides of the equation.

4(6x4)=4(6x)+(4)(4)=24x+16-4(6x - 4) = -4(6x) + (-4)(-4) = -24x + 16 (4x6)=4x+6-(4x - 6) = -4x + 6

So the equation becomes:

24x+16=4x+6+30-24x + 16 = -4x + 6 + 30

Step 2: Simplify the right-hand side

Now, simplify the right-hand side by combining like terms:

24x+16=4x+36-24x + 16 = -4x + 36

Step 3: Move all terms involving xx to one side

Add 24x24x to both sides to move the xx-terms to one side:

16=20x+3616 = 20x + 36

Step 4: Isolate the xx-term

Subtract 36 from both sides to isolate the term with xx:

1636=20x16 - 36 = 20x 20=20x-20 = 20x

Step 5: Solve for xx

Now, divide both sides by 20:

x=2020=1x = \frac{-20}{20} = -1

Final Answer:

x=1x = -1
