Therefore we can express x = 7/11 (x+y). Since we also know that the total of x+y is 88, we can substitute this into our x value. This means that x= 7/11 (88).Since 1/11 of 88 is 8, 7/11 is 8x7=56. Now that we have worked out the value of x, we can work out the value of y using the second equation in the question.
