Example Question #45 : One Step Equations With Fractions
Solve for in the following equation.
When solving for x, we need to get x alone. To do that, we need to multiply both sides by 4.
Multiply through.
Simplify.
Solution.
Example Question #41 : One Step Equations With Fractions
Find the solution for g.
This is a simple one-step equation. The objective is to solve for g and isolate it on the right side.
The steps are as follows:
You can check your answer by inserting g into the original equation as follows.
It works!
Example Question #41 : One Step Equations With Fractions
Solve for in the following equation:
When solving for x, we want to get x to stand alone. We subtract from both sides. We get
We must find a common denominator. In this case, the lowest common denominator is 4. So we get
Example Question #47 : One Step Equations With Fractions
Solve for in the following equation:
When solving for x, we must get x to stand by itself. Therefore, in the equation
we will add to both sides. We get
To add the fractions, we must find a common denominator.
In this case, it's 15.
So,
Example Question #42 : One Step Equations With Fractions
Solve for a in the following equation:
When solving for a, we want to get a by itself. So in the equation,
we must subtract from both sides. We get
When subtracting fractions, we need to find a common denominator. In this case, it's 6. So,
Now, we subtract the numerators and get
Example Question #851 : Pre Algebra
Solve the following equation:
None of the above.
This is a one-step problem in which you need to multiply both sides by to isolate "x."
You will then get:
The fives cancel and you are left with:
Example Question #852 : Pre Algebra
Solve for .
Perform the same operation on both sides of the equation.
It will be easier to write the right side of the equation as a fraction.
Now, we add two-fifths to both sides of the equation.
