translste the sentece into an equation and slove it.if 4 times a number is decreased by 9, the result is 19. find the number?
What is 4n-9=19
what is the number?
Do you want us to do all the work for you?
4n - 9 =19
Add nine to both sides and then divide both sides by 4.
To translate the given sentence into an equation and solve it, let's break it down step by step:
Step 1: Assign a variable to the unknown number.
Let's assume the unknown number is "x".
Step 2: Translate the sentence into an equation.
The sentence states, "4 times a number is decreased by 9, the result is 19." This can be written as:
4x - 9 = 19
Step 3: Solve the equation.
To solve this equation, we need to isolate the variable "x" on one side of the equation. Let's add 9 to both sides:
4x - 9 + 9 = 19 + 9
4x = 28
Now, let's divide both sides of the equation by 4 to isolate "x":
4x/4 = 28/4
x = 7
Step 4: Find the number.
So, the value of the unknown number is x = 7.
