In order to solve for m, you must subtract 9 from both sides. m + 9 = 87 - 9 -9 __________ 0 78 m = 78 You can check your work by substituting 78 in for m in the original equation: m + 9 = 87 78 + 9 = 87

Question:

The sum of two numbers is 36. The difference is 8. What are the two numbers?

Inactive

Let x be the first number. Let y be the second number. x + y = 36 x - y = 8 Now, solves the system of equations by elimination. Adding the left and right sides together give: x + x + y - y = 36 + 8 2x = 44 (Divide both sides by 2 to solve for x) x = 22 Since x + y = 36, 22 + y = 36 22 + y = 36 (Subtract 22 from both sides to solve for y) y = 14 The numbers are: x = 22, y = 14 x + y = 36 22 + 14 = 36
