Subtract 7 from the product of 4 and a number results in the number added to 29 is what

Let the unknown number be x.

"Subtract 7 from the product of 4 and a number"

4x - 7

"the number added to 29"

x + 29

Doing the first expression results in the second expression, so the expressions are equal.

4x - 7 = x + 29

Add 7 to both sides.

4x = x + 36

Subtract x from both sides.

3x = 36

Divide both sides by 3.

x = 12

The number is 12.

Check: Subtract 7 from the product of 4 and 12:

4 * 12 - 7 = 48 - 7 = 41

12 added to 29:

12 + 29 = 41

Both expressions equal 41, so 12 is the correct value for the number.

- both graphs increase on their domain.

- the graphs of both functions have the same x-intercept.

- neither graph has a y-intercept.
