Answer 1

Відповідь:

-20

Покрокове пояснення:

12-3/5х=29+1/4х

-12х + 240 = 5х + 580 х = -20

Answer 2

To solve the equation 12 - (3/5)x = 29 + (1/4)x, we can follow these steps:

Step 1: Simplify the equation by combining like terms on both sides of the equation. - On the left side, we have 12 - (3/5)x. - On the right side, we have 29 + (1/4)x.

Step 2: To eliminate the fractions, we can multiply the entire equation by the least common multiple (LCM) of the denominators, which is 20 in this case.

Step 3: Multiply each term by 20: - (20 * 12) - (20 * (3/5)x) = (20 * 29) + (20 * (1/4)x). - Simplifying further, we get 240 - 12x = 580 + 5x.

Step 4: Combine like terms: - Subtract 5x from both sides: 240 - 12x - 5x = 580 + 5x - 5x. - Simplifying further, we get 240 - 17x = 580.

Step 5: Move all the variables to one side and the constants to the other side: - Add 17x to both sides: 240 - 17x + 17x = 580 + 17x. - Simplifying further, we get 240 = 580 + 17x - 17x. - Combine like terms, we get 240 = 580.

Step 6: Solve for x: - Since 240 is not equal to 580, there is no solution to this equation.

Therefore, the equation 12 - (3/5)x = 29 + (1/4)x has no solution.

I hope this helps! Let me know if you have any further questions.
