Math Problem Statement

(2/3)×(x-3) = x/4

Solution

To solve the equation 23(x3)=x4\frac{2}{3}(x - 3) = \frac{x}{4}, follow these steps:

Step 1: Eliminate the fractions

Multiply both sides of the equation by the least common denominator (LCD) of 3 and 4, which is 12, to get rid of the fractions.

12×23(x3)=12×x412 \times \frac{2}{3}(x - 3) = 12 \times \frac{x}{4}

This simplifies to:

4×2(x3)=3x4 \times 2(x - 3) = 3x

8(x3)=3x8(x - 3) = 3x

Step 2: Distribute

Now distribute the 8 on the left-hand side:

8x24=3x8x - 24 = 3x

Step 3: Move all terms involving xx to one side

Subtract 3x3x from both sides:

8x3x24=08x - 3x - 24 = 0

This simplifies to:

5x24=05x - 24 = 0

Step 4: Solve for xx

Add 24 to both sides:

5x=245x = 24

Now, divide by 5:

x=245x = \frac{24}{5}

So, the solution is:

x=245orx=4.8x = \frac{24}{5} \quad \text{or} \quad x = 4.8
