Example Question #1 :How To Find Out When An Equation Has No Solution
Find the solution to the following equation if x = 3:
y = (4x2- 2)/(9 - x2)
3
6
no possible solution
0
no possible solution
Substituting 3 in for x, you will get 0 in the denominator of the fraction. It is not possible to have 0 be the denominator for a fraction so there is no possible solution to this equation.

A fraction is considered undefined when the denominator equals 0. Set the denominator equal to zero and solve for the variable.
# 47例问题:Algebra
Solve:
First, distribute, making sure to watch for negatives.
Combine like terms.
Subtract 7x from both sides.
Add 18 on both sides and be careful adding integers.
Example Question #48 :Algebra
Solve:
No Solution
Infinitely Many Solutions
No Solution
First, distribute theto the terms inside the parentheses.
Add 6x to both sides.
This is false for any value of. Thus, there is no solution.
Example Question #41 :Algebra
Solve.
No solutions
No solutions
By definition, the absolute value of an expression can never be less than 0. Therefore, there are no solutions to the above expression.
Example Question #1 :How To Find Out When An Equation Has No Solution
,
In the above graphic, approximately determine the x values where the graph is neither increasing or decreasing.
We need to find where the graph's slope is approximately zero. There is a straight line between the x values of, and. The other x values have a slope. So our final answer is.
