Math Problem Statement

Solve the equation: (x - 4)/5 = 9 - (2x - 41)/9

Solution

The equation extracted from the image seems to be:

x45=92x419\frac{x - 4}{5} = 9 - \frac{2x - 41}{9}

Now, let's solve this step-by-step.

Step 1: Eliminate the fractions

To clear the denominators, multiply the entire equation by the least common denominator (LCD), which is 45 (LCM of 5 and 9).

45×x45=45×(92x419)45 \times \frac{x - 4}{5} = 45 \times \left(9 - \frac{2x - 41}{9}\right)

This simplifies to:

9(x4)=45×95(2x41)9(x - 4) = 45 \times 9 - 5(2x - 41)

Step 2: Expand both sides

Now expand both sides:

9x36=40510x+2059x - 36 = 405 - 10x + 205

Simplify:

9x36=61010x9x - 36 = 610 - 10x

Step 3: Collect like terms

Move all the xx terms to one side and the constants to the other side:

9x+10x=610+369x + 10x = 610 + 36

19x=64619x = 646

Step 4: Solve for xx

Divide both sides by 19:

x=64619=34x = \frac{646}{19} = 34

Thus, the solution is:

x=34x = 34
