if - 2 x + 3 y = 8 and 4 x - 3 y = 20 , what is the sum of x and y ?
"given - 2 x + 3 y = 8 - - - eq 1 4 x - 3 y = 20 - - eq 2 sum both eqns we get 2 x = 28 = > x = 14 sub 2 x in eq 1 = > - 28 + 3 y = 8 . = > y = 12 now x + y = 12 + 14 = 26 option d is correct answer ."
multiply(divide(add(20, multiply(divide(add(8, 20), 3), 3)), 2), divide(add(8, 20), 3))
