00:04 We want to isolate the unknown X
00:07 Let's properly open the parentheses, multiply by each factor
00:22 Divide 16 by 4
00:26 Negative times positive is always negative
00:37 Let's isolate the unknown X
00:53 Let's reduce what we can, group the factors
01:06 Let's isolate the unknown X

Step-by-Step Solution

To solve this problem, we'll follow these steps:

  • Step 1: Distribute 16 across the expression inside the parentheses.
  • Step 2: Simplify the equation by moving all terms involving x x to one side and constant terms to the other side.
  • Step 3: Solve for x x by isolation through arithmetic manipulation.

Now, let's work through each step:
Step 1: Start by distributing 16 on the left-hand side:

16×(14x2)=16×14x16×2 16 \times \left( \frac{1}{4}x - 2 \right) = 16 \times \frac{1}{4}x - 16 \times 2

Simplifying each term gives you:

4x32 4x - 32

Now the equation is:

4x32=3x+12 4x - 32 = 3x + \frac{1}{2}

Step 2: Rearrange to collect like terms, move 3x 3x to the left side by subtracting it from both sides:

4x3x32=12 4x - 3x - 32 = \frac{1}{2}

This simplifies to:

x32=12 x - 32 = \frac{1}{2}

Step 3: Isolate x x by adding 32 to both sides:

x=12+32 x = \frac{1}{2} + 32

Converting to a common denominator and performing the addition:

x=12+642 x = \frac{1}{2} + \frac{64}{2} x=652 x = \frac{65}{2}

Finally, convert this fraction to a mixed number:

x=3212 x = 32\frac{1}{2}

Therefore, the solution to the problem is x=3212 x = 32\frac{1}{2} .

Answer

3212 32\frac{1}{2}
