Answer :
The equation is 4(n - 7) = 88 and the value of n is 29.
What is an Equation?
An equation basically means a mathematical statement including variables and operator that shows that two expressions are equal. Any equation can be solved using PEMDAS rule. where P stands for Parenthesis, E stands for Exponents, D stand for Divide, M for Multiplication, A for Addition and S for Subtraction.
If the number n is decreased by 7, that means n - 7.
Then the result is multiplied by 4, so 4(n - 7).
The product is equal to 88, so the equation is,
4(n - 7) = 88
Now, solving the equation
4(n - 7) = 88
4n - 28 = 88
4n = 116
n = 29
Therefore, the equation is 4(n - 7) = 88 and the value of n is 29.
