Hello from MrBillDoesMath!

Answer:

a = 15



Discussion:

Division precedes subtraction ( order of operations) so


a/3-1 =4                              =>   is equivalent to

(a/3) - 1 = 4                         =>   add 1 to both sides

(a/3) - 1 + 1 = 4 + 1 = 5       =>   multiply both sides by 3

(a/3)* 3  = 5*3 = 15            =>

a = 15

Thank you,

MrB
