2x - 20 = 50 is the equation. "Twice" means 2 times, "decreased by" means subtraction, and "is" means equals. Do the math; it's easy now.

two years of local internet service cost $685 including the installation fee of $85 what is the monthly fee?
zimovet [89]
2 years is the same as 24 months, so the equation would be:
685 = 24x + 85, where x is the monthly fee.
600 = 24x
600/24 = x
x = 25
The monthly fee is $25.
