The rainfall this year was 18.6 centimeters. this is 3.2 centimeters less than half of the rainfall last year. what was the rainfall last year?

Let, rainfall of last year = x

A.T.Q,

x/2 - 3.2 = 18.6

x/2 = 18.6+3.2

x/2 = 21.8

x = 21.8*2

x = 43.6

x = 2

Step-by-step explanation:

Given

See attachment

Required

What is the value of x?

The vertical axis represents f(x) while the horizontal represents x.

From the attachment:

f(x) = 2 when x = 2

The circled point on attachment 2 represents the required point

Assume that each box is 1 unit.
