Question

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

Answer 1

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

Answer: 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.

Answer 2

4x-7=29 < do you understand how to set that up? Now, the goal is to “get x by itself.”

4x-7=29< now add the 7 to the 29. When you cross an equals sign you change the (+/-) sign of the number you’re moving.

4x= 36< now you will just divide by 4 on both sides. This will give you x by itself on the left side of the equals sign.

x=36/4 which is 9

X=9 :))
