Step-by-Step Solution

Let's solve for x x step by step:

First, we rewrite the given equation:
638x+624x=58x+73 6 - \frac{3}{8}x + \frac{6}{24}x = \frac{5}{8}x + 7 - 3 .

Simplify the terms:
624x\frac{6}{24}x simplifies to 14x\frac{1}{4}x.

Rewrite the equation:
638x+14x=58x+4 6 - \frac{3}{8}x + \frac{1}{4}x = \frac{5}{8}x + 4 .

Convert 14\frac{1}{4} to 28\frac{2}{8} to combine the terms:
638x+28x=58x+4 6 - \frac{3}{8}x + \frac{2}{8}x = \frac{5}{8}x + 4 .

Combine like terms on the left:
618x=58x+4 6 - \frac{1}{8}x = \frac{5}{8}x + 4 .

Move all terms involving x x to one side and constants to the other:
Subtract 58x\frac{5}{8}x from both sides:
618x58x=4 6 - \frac{1}{8}x - \frac{5}{8}x = 4 .

Combine the x x -terms:
668x=4 6 - \frac{6}{8}x = 4 .

Simplify 68\frac{6}{8} to 34\frac{3}{4}:
634x=4 6 - \frac{3}{4}x = 4 .

Subtract 6 from both sides to isolate the term with x x :
34x=46-\frac{3}{4}x = 4 - 6 .

Solve the constant:
34x=2-\frac{3}{4}x = -2 .

Divide both sides by 34-\frac{3}{4} to solve for x x :
x=234=2×43=83 x = \frac{-2}{-\frac{3}{4}} = \frac{-2 \times 4}{-3} = \frac{8}{3} .

Therefore, the solution to the equation is x=83 x = \frac{8}{3} .

Answer

83 \frac{8}{3}
