If the question is to solve the system of the equations of two variables, then:
Let y = f(x) = 2x - 5, and
let y = g(x) = -3x - 1
So we have:
y = 2x - 5
y = -3x - 1
2x - 5 = -3x - 1
2x + 3x -5 + 5 = -3x + 3x - 1 + 5
5x = 4
x = 4/5
y = 2x - 5
y = 2(4/5) - 5
y = 8/5 - 5
y = 8/5 - 5 x 5/5
y = 8/5 - 25/5
y = (8 - 25)/5
y = -17/5
Thus, the solution of the system is x = 4/5 and y = -17/5.

How do you find out if y is a function of x?
y is a function of x iffor each value of x (in the domain) there is a value of y, andfor each value of y (in the range) there is at most one value of x.

How do you find maximum revenue using quadratic equations?
Suppose the revenue equation is of the form R = ax2 + bx + c where a, b and c are constants and x is the variable. To have a maximum, either a must be negative or x must lie within fixed limits. If a is negative then the maximum revenue is attained when x = -b/(2a). That is, find the value of R when x = -b/(2a). If a is positive, then find the value of R when x is at each end point of its domain. One of them will be larger and that is the maximum value of the revenue.
what is predecessor?
As discussed in the introduction, a predecessor is a value that comes right before/immediate before/just before a particular value. Suppose a value is x (where x belongs to any whole number), then the predecessor of x will be x-1. Thus, to find the predecessor of any value, we have to subtract the given value from 1.
