Find the length of x

Step-by-step explanation:

We will use a proportion to solve this. All we need are two corresponding values. One is x and 7, we'll pick the other as 32 and 4.

Now, we'll set up the proportion

To solve a proportion, we cross multiply the means and extremes.

4x = 32 x 7

4x = 224

x = 56

We can check the proportion by substituting our answer in for x and seeing if the products equal. If they do, we know we have the correct answer.

4(56) = 32 x 7

224 = 224 ✅
