Answer» Step-by-step EXPLANATION: Below is an IMAGE of a venn diagram that can be used when solving this question. To find the value of x, we must do the following: (72 - x) + x + (43 - x) = 100 72 - x + x + 43 - x = 100 72 + 43 - x = 100 115 - x = 100 -x = 100 - 115 x = 15 Now, we have SUB in the value of x to find how MANY people speak ENGLISH and French. Only English: 72 - x = 72 - 15 = 57 Only French: 43 - x = 43 - 15 = 28 Both English and French = x = 15

Step-by-step EXPLANATION:

Below is an IMAGE of a venn diagram that can be used when solving this question.

To find the value of x, we must do the following:

(72 - x) + x + (43 - x) = 100

72 - x + x + 43 - x = 100

72 + 43 - x = 100

115 - x = 100

-x = 100 - 115

x = 15

Now, we have SUB in the value of x to find how MANY people speak ENGLISH and French.

Only English: 72 - x = 72 - 15 = 57

Only French: 43 - x = 43 - 15 = 28

Both English and French = x = 15
