To find the inverse of a function switch the place of y (aka f(x) ) with x. Then solve for y.
Original equation:
y = 2x + 17
Switched:
x = 2y + 17
Solve for y by isolating it:
x - 17 = 2y + 17 - 17
x - 17 = 2y
(x - 17)/2 = 2y/2

Answer:
27 and 32.
Step-by-step explanation:
Let the two numbers be A and B.
The larger number (let's use B) is 5 more than the smaller one (A). In other words:
Their sum is 59. So:
This is a system of equations. Solve by substituting the first equation into the second. Thus:
Combine like terms:
Subtract 5 from both sides:
Divide both sides by 2:
So, the smaller number is 27.
This means that the bigger number is 27+5=32.
So, the two numbers are 27 and 32.
And we're done!
