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 :))

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.
