Substitute x with (-2) and y with (-4)
simplify: 5(41 - x) + {-7(y + x)} =

The value which is obtained on simplifying the expression is:

We are asked to simplify the expression which is given in terms of two variables x and y as follows:

Now, we have to simplify the expression for the values of x and y as follows:

On putting these values in the given expression:

first, we define the variables:

x: number of years after 1950

f (x): amount of vinyl sold.

then, with the variables defined, we have:

68594 vinyl records were sold in 1958 > f (8) = 68594

91299 vinyl records were sold in 1961 > f (11) = 91299

38720 vinyl records were sold in 1952 > f (2) = 38720

161743 vinyl records were sold in 1967 > f (17) = 161743
