x + 3 + 4x = 23
What is x?
x + 3 + 4x = 23
5x + 3 = 23
5x = 20
x = 4
To find the value of x in the equation x + 3 + 4x = 23, we need to isolate x on one side of the equation. Here's how:
Step 1: Combine like terms
Combine the x terms together:
x + 4x = 5x
Step 2: Simplify the equation
Now the equation becomes:
5x + 3 = 23
Step 3: Isolate the variable
To isolate x, subtract 3 from both sides of the equation:
5x + 3 - 3 = 23 - 3
5x = 20
Step 4: Solve for x
To solve for x, divide both sides of the equation by 5:
5x/5 = 20/5
x = 4
Therefore, the solution to the equation x + 3 + 4x = 23 is x = 4.
