Solving for the Variable - GED Math

Collect the like terms by subtracting from both sides:

Isolate on the right by dividing both sides by . Reverse the direction of the inequality symbol, since you are dividing by a negative number:

The solution set is .

First, distribute the 9 on the left by multiplying it by each expression in the parentheses:

Isolate on the right by first, subtracting 162 from both sides:

Divide both sides by 9:

The correct solution set is .

or, in interval form,

In interval form, this is .

Solve using the properties of inequality, as follows:

Note that division by a negative number reverses the symbols.

In interval form, this is .

Rewrite the algebraic expression in a mathematical formula.

Solve for x.

The square of this number is:

In order to solve for the value of you must isolate the variable. This is done by subtracting the constant in this equation, which is 12, from both sides of the equation.

The first step in the process of solving for in this problem is to use the distributive property to distribute the to what is inside the parentheses.

The next step is to isolate the variable by using inverse operations. In this example, in order to get rid of the , you would add to both sides of the equation.

The next step is to divide both sides by the coefficient, (the number next to the variable), which in this case is .

To solve this you must find the value of .

The first equation states that . This is a mult-step equation. The first step is to remove the constant, 6, from the equation; this is done by using the inverse operation, which means you would subtract the 6 from both sides of the equation.

Then divide both sides by the 7 in order to isolate the variable.

Then plug the 3 into the second equation for the value of x.

Since the original statement forces this false statement to be true, the original statement is false regardless of the value of . There is no solution.
