Answer:

  • a=50
  • b=45

Step-by-step explanation:

We can subtract the second equation from 4 times the first:

  4(a +b) -(4a +1.5b) = 4(95) -(267.5)

  2.5b = 112.5 . . . . . simplify

  b = 45 . . . . . . . . . . divide by 2.5

  a = 95 -b = 50 . . . find 'a'

The solution is (a, b) = (50, 45).
