Question

The temperature in San Diego, California is 5 degrees warmer than twice the temperature in Boise, Idaho. The temperature in San Diego is 61 degrees. Write an equation to determine the temperature in Boise.

Answer 1

2x + 5 = 61

Explanation:

Let x be equal to the temperature in Boise.

Since the temperature in San Diego is 5 degrees warmer than twice the temperature in Boise, we must double the temperature in Boise and then add 5 degrees. To do this we put a 2 in front of the x and then add 5 to that.

2x + 5

Since we know the temperature in San Diego is 61 we can make the equation equal to 61.

2x + 5 = 61
