Jill is thinking of a number. Twenty less than one fourth of the number is -45. Find Jill's number.
x = the number
x/4 - 20 = -45 {twenty less than one-fourth of the number is -45}
x/4 = -25 {added 20 to each side}
x = -100 {multiplied each side by 4}
The number is -100, Jill can think of something else, now.
