How do you solve 132=3(5n+4)

To solve this, you need to isolate/get the variable "n" by itself in the equation:

132 = 3(5n + 4)        First divide 3 on both sides

44 = 5n + 4     Subtract 4 on both sides

44 - 4 = 5n + 4 - 4

40 = 5n         Divide 5 on both sides to get "n" by itself

8 = n

PROOF

132 = 3(5n + 4)     Substitute/plug in 8 into "n" since n = 8

132 = 3(5(8)+4)

132 = 3(40 + 4)

132 = 3(44)

132 = 132
