5 times a number decrease by 18 minus 4 times the same number is -36
what is the number
5n - 18 - 4n = -36
n = 18
Let's assume the number is represented by "x".
According to the given information:
5 times a number decrease by 18: 5x - 18
Minus 4 times the same number: -4x
Equals -36: = -36
Combining these equations, we get:
5x - 18 - 4x = -36
Simplifying the equation:
x - 18 = -36
Adding 18 to both sides of the equation:
x - 18 + 18 = -36 + 18
Simplifying further:
x = -18
Therefore, the number is -18.
To solve for the number in the given equation, let's define the unknown number as "x."
The given equation is:
5x - 18 - 4x = -36
To solve this equation, follow these steps:
Step 1: Combine like terms on the left side of the equation:
(5x - 4x) - 18 = -36
x - 18 = -36
Step 2: Add 18 to both sides of the equation to isolate the variable:
x - 18 + 18 = -36 + 18
x = -18
Therefore, the number is -18.
