if 4 x + 3 y = 8 and y - 3 x = 8 , then what is the value of x + 4 y ?
"4 x + 3 y = 8 . . . equation 1 - 3 x + y = 8 . . . equation 2 adding both the equations x + 4 y = 16 correct answer option b"
multiply(divide(add(const_60.0, 4), add(3, 4)), divide(subtract(multiply(3, divide(add(8, 4), add(3, 4))), 4), 3))
