Math Problem Statement

-2/5x + 3 = 2/3x +1/3

Solution

Let's solve the equation:

25x+3=23x+13-\frac{2}{5}x + 3 = \frac{2}{3}x + \frac{1}{3}

Step 1: Eliminate the fractions

To clear the fractions, find the least common denominator (LCD) of 5 and 3, which is 15. Multiply both sides of the equation by 15:

15(25x+3)=15(23x+13)15\left(-\frac{2}{5}x + 3\right) = 15\left(\frac{2}{3}x + \frac{1}{3}\right)

Distribute 15 on both sides:

15×25x+15×3=15×23x+15×1315 \times -\frac{2}{5}x + 15 \times 3 = 15 \times \frac{2}{3}x + 15 \times \frac{1}{3}

This simplifies to:

6x+45=10x+5-6x + 45 = 10x + 5

Step 2: Move the variables to one side

Now, subtract 10x10x from both sides:

6x10x+45=5-6x - 10x + 45 = 5

Simplifying:

16x+45=5-16x + 45 = 5

Step 3: Isolate xx

Subtract 45 from both sides:

16x=545-16x = 5 - 45

Simplifying:

16x=40-16x = -40

Step 4: Solve for xx

Divide both sides by -16:

x=4016x = \frac{-40}{-16}

Simplify the fraction:

x=4016=52x = \frac{40}{16} = \frac{5}{2}

Final Answer:

x=52x = \frac{5}{2}
