Can someone explain to me how the x in w(x) = 3x - 7 if w(x) = 14 is 7?

Let w(x) = 3x - 7 if w(x) = 14, find x.

Answer:

see explanation

Step-by-step explanation:

given w(x) = 3x - 7 and w(x) = 14 then equating the two gives

3x - 7 = 14 ( add 7 to both sides )

3x = 21 ( divide both sides by 3 )

x = 7
