Answer:
-37
Step-by-step explanation:
Simplifying
74 + 2x = 0
Solving
74 + 2x = 0
Move all terms containing x to the left, all other terms to the right.
Add '-74' to each side of the equation.
74 + -74 + 2x = 0 + -74
Combine like terms: 74 + -74 = 0
0 + 2x = 0 + -74
2x = 0 + -74
Combine like terms: 0 + -74 = -74
2x = -74
Divide each side by '2'.
x = -37
Simplifying
x = -37

What we know:
Carpet cleaner a charges $28.25 plus $18 a room. Carpet cleaner B charges $19.85 Plus $32 a room.
What we need to find:
Which equation can be used to find the number of rooms for which the total cost of both carpet cleaners is the same?
28.25 + 18x=19.85 + 32x
To simplify a fraction (reduce it to lowest terms), you divide
the numerator and denominator both by their greatest common
factor. (That's why you learn 'greatest common factor' before
you learn to simplify fractions.)
The greatest common factor of 36 and 80 is 4 .
Divide the top and bottom of 36/80 by 4, and you'll have the
fraction in lowest terms.
