Question

19-x=20+5/9x ????????????????

Answer 1

19-x=20+5/9x

1) 171-9x=180+5x

2) -9x-5x=180-171

3) -14x=9

4) x= -9/14

Ответ: -9/14

Answer 2

To solve the equation 19 - x = 20 + (5/9)x for x, follow these steps:

Step 1: Distribute the (5/9)x term on the right side of the equation: 19 - x = 20 + (5/9)x 19 - x = 20 + 5x/9

Step 2: Get rid of the fractions by multiplying both sides of the equation by 9 (the denominator of the fraction): 9(19 - x) = 9(20 + 5x/9) 171 - 9x = 180 + 5x

Step 3: Move the terms involving x to one side of the equation and the constants to the other side: -9x - 5x = 180 - 171 -14x = 9

Step 4: Solve for x by dividing both sides by -14: x = 9 / -14

So, the solution for the equation 19 - x = 20 + (5/9)x is approximately: x ≈ -0.6429
