Directions: For each problem below, use four of the whole numbers 1 through 9 no more than one time each to find the the greatest value for x that you can.

### Hint

### Hint

Where shoud the 9 go or not go? Where should the 1 go or not go? Explore “Two-Step Equations” problem first. How can we use our learning from that problem to tackle this problem?

### Answer

### Answer

(1/8)x + 2 = 9 yields a solution of 56.

(1/9)x – 8 = 7 and (1/9)x – 7 = 8 both have a solution of 135.
