I added 18 to 3 times a number the result is equal to 4 time the number. what is the number
Let's use algebra to solve the problem:
18 + 3x = 4x
Subtracting 3x from both sides:
18 = x
Therefore, the number is 18.
Let's use algebra to solve the problem:
18+3x=4x
Subtracting 3x from both sides
x=18
Therefore the number is 18
That's correct! Well done.
To find the number in this equation, let's break it down step by step.
The equation given is:
18 + 3 times a number = 4 times the number
Let's assume the number is represented by the variable 'x'. We can rewrite the equation using algebraic notation:
18 + 3x = 4x
To solve for 'x', we will isolate the variable on one side of the equation by performing algebraic operations. Let's subtract '3x' from both sides of the equation:
18 = 4x - 3x
Simplifying further, we get:
18 = x
Therefore, the number, represented by 'x', is equal to 18.
