:
Let x = the number and just write an equation for what it says:
:
If four times the sum of a number and 5, is divided by 3, the result is 16
%284%28x+%2B+5%29%29%2F3 = 16
Multiply equation by 3:
4(x + 5) = 3(16)
:
4x + 20 = 48
:
4x = 48 - 20
:
4x = 28
x =28%2F4
x = 7
:
:
Check solution in original equation:
%284%287+%2B+5%29%29%2F3 = 16
%284%2812%29%29%2F3 = 16
48%2F3 = 16
