solve:
4x+18=22
please help. i just need to understand how to do this for i have many problems like this on my final, and i have forgotten how!
You want everything with x in it on the left and everything without x on the right
So
add -18 to both sides
then divide both sides by 4 to get 1x instead of 4x
4x+18=22
First, subtract the known number on the left side from each side of the equation.
4x + 18 - 18 = 22 - 18
4x = 4
Divide both sides of the equation by 4.
x = 1
Let's prove it.
4 * 1 + 18 = 22
Yep. It's right!
To solve the equation 4x + 18 = 22, you need to isolate the variable x. Here's how you can do it step by step:
Step 1: Simplify the equation.
Start by subtracting 18 from both sides to move the constant term to the right side of the equation:
4x + 18 - 18 = 22 - 18.
This simplifies to:
4x = 4.
Step 2: Solve for x.
To solve for x, divide both sides of the equation by 4:
(4x) / 4 = 4 / 4.
This simplifies to:
x = 1.
So the solution to the equation 4x + 18 = 22 is x = 1.
If you have multiple problems like this, you can follow the same process for each equation. Remember to isolate the variable by performing the inverse operation of each term in the equation.
