the sum of three times the larger of the two integers and twiec the smaller integer is -19. the difference between the two integer is 7. What are the integers?
The sum (addition) of 3× the larger (y) + 2× the smaller (x) = -19 The difference (subtraction) between x & y (y-x) = 7 3y + 2x = -19 y - x = 7 y = x + 7 Substitution 3(x+7) + 2x = -19 3x+21 + 2x= -19 5x +21-21 = -19-21 5x/5 = -40/5 x = -8 y = x+7 = -8+7 = -1
