Determine whether an equation written with one operation can be rewritten as an equivalent equation using a different operation. Choose True or False for each statement. Multiplication and division are inverse operations. Choose... The equation 3x = 12 can be rewritten as x = 12 ÷ 3. Choose... Addition and subtraction are inverse operations. Choose... The equation x + 1.793 = 2.42 can be rewritten as x – 1.793 = 2.42 – 1.793. Choose...

hello from mrbilldoesmath!

answer:

a(n) - a(n-1) -3

discussion:

this ones a bit interesting. given a(n) = 5 - 3n consider this:

a(n-1) = 5 - 3(n-1)

          = (5 - 3n) + 3             => but a(n) = 5 - 3n, the first term

          = a(n)   + 3                 => subtract 3 from both sides

a(n-1) -3 = a(n)  

or

a(n) - a(n-1) -3
