Let's let the question mark be represented by x. We get the equation \frac{7}{8}x=21. We need to solve for x, and we can do that by first multiplying the reciprocal of \frac{7}{8}, which is \frac{8}{7}. When we multiply and simplify, we get that x=24. Therefore, the value of the question mark that makes the equation \frac{7}{8}?=21 true is \boxed{24}.

Six times a number is 45 greater than the the product of the number and -3. Find the number.
blagie [28]

Let us try to formulate the expressions one by one.

let the number be x.

Step 1:

six time the number is 6*x = 6x

Step 2:

product of the number and -3 is -3x

Step 3:

now let us make equation for it:

6x = -3x +45

adding 3x on the left side,

6x+3x = 45

9x = 45

dividing right side by 9

x=45/9 = 5

So the number is x=5
