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.

2x + 5 = 61

Step-by-step 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

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.
