Let f(x) be y so you have
y=7x-13
Reverse the signs of x and y so you have
x=7y-13
And then find the value of y
x+13=7y
(x+13)/7=y
And change y to f(x)-1
If I read your question right, an equivalent expression would be 15s-10 after distributing the 5.
The answer is 10 2/11. I hope this helps!
Answer:
12 hours
Step-by-step explanation:
Let x be the amount of money he makes in 1 hour
324=18x
x=18
So, we know that 18 time the number of hours will be 216
Let y be the number of hours
18y=216
y=12
