2. Solve. All changes The sum of two numbers is 70 and their difference is 30. Find the two numbers using the process of substitution. Letr = the first number and y= the second number. Write an equation showing the sum of the numbers: a Write an equation showing the difference of the numbers: d a. I ty=I - y b. 70.x - 30y = 40 C. 70x + 30y = 100 d. I-y=30 e. I+y= 70 3 Salve PREVIOUS 1-10 of 10 ENEO REVIE
