The following equation has denominators that contain variables. for this equation write the value or values of the variable that make a denominator zero. these are the restrictions on the variable. keeping the restrictions in mind, solve the equation.
2/11x plus 1/4 equals 81/22x-1/3
x=
To find the restrictions on the variable, we need to identify the values that make any of the denominators in the equation equal to zero.
For the given equation:
2/(11x) + 1/4 = 81/(22x) - 1/3
The denominators are 11x, 4, 22x, and 3.
Setting each denominator equal to zero, we can solve for x:
1) 11x = 0
Divide both sides by 11: x = 0
2) 4 = 0
No solution, since 4 is a constant and cannot be equal to zero.
3) 22x = 0
Divide both sides by 22: x = 0
4) 3 = 0
No solution, since 3 is a constant and cannot be equal to zero.
Therefore, the restrictions on the variable x are x ≠ 0.
To solve the equation, we need to simplify each side by finding a common denominator:
Multiply every term on the left side by 4 to get:
(2/11x) * 4 + 1/4 * 4 = 81/(22x) * 4 - 1/3 * 4
8/(11x) + 1 = 324/(22x) - 4/3
Now, multiply every term by 66x to eliminate the denominators:
66x * (8/(11x) + 1) = 66x * (324/(22x) - 4/3)
(528 + 66x) = (3564 - 88x)
Combine like terms:
154x = 3036
Divide both sides by 154:
x = 3036/154
Now simplify the fraction:
x = 18/7
Therefore, the solution to the equation, considering the restrictions on the variable, is x = 18/7.
