4(x-3) = 81

Divide by 4.

(x - 3) = 81/4

Add 3

x = 81 / 4 + 3
x = 81 /4 + 12/4
x = 93 / 4

x = 81 / 4 + 3
x = 81 /4 + 12/4
x = 93 / 4

you distribute the 4 to the x and the -3 which equals 4x-12=81 then you do the inverse opperation, you have to do the one that is not connected to the 4 first so you will add 12 to both sides because you have to do the same thing to both sides, so that will be

4x-12=81
+12 +12


then you cancel the 12s on the left making your equation
4x=93
then you divide both sides by 4
x=93/4
x=23.5


4(x-3)=81
4x-12=81
4x=93
x=23.25

You can multiply it out by the Distributive Property to get 4x - 12 = 81,

then add 12 to both sides then divide both sides by 4

4(x-3)=81~Divide by 4 on both sides
x-3=20.25~Add 3 on both sides
x=23.25 or 23 1/4

(x-3) = 81/4 = 20.25
x = 20.25+3 = 23.25
