Math Problem Statement

Solve the equation: x/2 + 2/5 = 5/6

Solution

You provided an equation that looks like this:

x2+25=56\frac{x}{2} + \frac{2}{5} = \frac{5}{6}

Let's solve it step by step.

Step 1: Isolate the variable term

First, subtract 25\frac{2}{5} from both sides:

x2=5625\frac{x}{2} = \frac{5}{6} - \frac{2}{5}

Step 2: Find a common denominator for the fractions

The denominators are 6 and 5, so the least common denominator is 30.

56=2530,25=1230\frac{5}{6} = \frac{25}{30}, \quad \frac{2}{5} = \frac{12}{30}

Now, subtract the fractions:

25301230=1330\frac{25}{30} - \frac{12}{30} = \frac{13}{30}

So we have:

x2=1330\frac{x}{2} = \frac{13}{30}

Step 3: Solve for xx

To solve for xx, multiply both sides of the equation by 2:

x=2×1330=2630=1315x = 2 \times \frac{13}{30} = \frac{26}{30} = \frac{13}{15}

Final Answer:

x=1315x = \frac{13}{15}
