Solve the systems of equations by any method that you choose. Eqi: 2x – 3y = 1
Eq2: x + 2y = -3
Please select the correct solution.

answer: 1) twenty-seven times y

              2) twenty-seven multiplied by y

an = 22 + (n-1) *6

110 seats

step-by-step explanation:

an=a1+(n-1)(d)

a1 = 22   this is the first item in the sequence

d =6   this is how the sequence goes up

a)   an = 22 + (n-1) *6

b) a12 = 22 + (12-1) *6

    a12 = 22+11*6

  a12 = 22 +88

  a12 = 110
