-26 times a number minus 22 is equal to 90 less than the number.
IgorLugansk [536]

Answer:

x = \frac{68}{27}

Step-by-step explanation:

Let x be the number

  1. Write it out: -26x - 22 = x - 90
  2. Combine like terms: -27x + 68 = 0
  3. Subtract 68 from each side, so it now looks like this: -27x = -68
  4. Divide each side by -27 to cancel out the -27 next to x. It should now look like this: x = \frac{68}{27}  

I hope this helps!
