Example Question #81 : How To Solve Two Step Equations
Solve for when
To solve for , first divide both sides of the equation by
:
Take the square root of both sides of the equation:
However, remember that is also equal to
, so the answer is both positive and negative
.
Example Question #82 : How To Solve Two Step Equations
What is if
?
Plugging in for
gives
.
=
= .
Example Question #83 : How To Solve Two Step Equations
Solve for :
This equation can be solved in three steps.
First, subtract from both sides of the equation to isolate the variable and its coefficient on the left side of the equation.
Now multiply both sides by since
cannot be solved for while it is in the denominator.
Finally, divide both sides by to isolate
and find the solution.

Example Question #2 : How To Solve Two Step Equations With Fractions In Pre Algebra
Solve for .
From here, you can either plug this into your calculator, or take the equation in pieces:
Example Question #2 : How To Solve Two Step Equations With Fractions In Pre Algebra
Solve for .
To solve , first we need to get rid of the fraction. Dividing by a fraction is the same as multiplying by a reciprocal, so multiply both sides by
.
Subtract from both sides.
Example Question #1 : How To Solve Two Step Equations With Fractions In Pre Algebra
Solve for .
To solve , we need to get rid of the fraction. To do that, we multiply both sides by the reciprocal of that fraction.
From here, you can either plug that fraction into your calculator or solve in pieces.
Example Question #6 : How To Solve Two Step Equations With Fractions In Pre Algebra
Solve for .
To solve for , we need to isolate our variable. That means that we want ONLY the
on the left side of the equation.
First, combine our like terms on the right side.
Now divide both sides by . Remember, dividing by a fraction is the same as multiplying by the reciprocal, so we're going to multiply both sides by
.
Since , we can ignore it.
