Explanation: Hello Students, time to practice and review the steps for the problem.

Lesson Steps

Steps	Problem	Solution
1	Solve	\$ 11/x^2 + 1/x - 2/x^2 = 6/x \$
2	Taking like terms together	\$ 11/x^2 - 2/x^2 = 6/x - 1/x \$
3	After simplification	\$ 9/x^2 = 5/x \$
4	Multiplying on both sides with \$ x^2 \$	\$ 9/\cancel(x^2) \cancel(x^2) = 5/\cancel(x) \cancel(x^2)^x \$
5	After simplification	\$ 9 = 5x\$
6	Dividing on both sides by '\$ 5 \$' of the equality	\$ 9/5 = \cancel(5)/\cancel(5)x \$
7	After cancelation	\$ x = 9/5 \$
8	Answer	C = \$ x = 9/5\$

Steps

Problem

Solution

Solve

\$ 11/x^2 + 1/x - 2/x^2 = 6/x \$

Taking like terms together

\$ 11/x^2 - 2/x^2 = 6/x - 1/x \$

After simplification

\$ 9/x^2 = 5/x \$

Multiplying on both sides with \$ x^2 \$

\$ 9/\cancel(x^2) \cancel(x^2) = 5/\cancel(x) \cancel(x^2)^x \$

After simplification

\$ 9 = 5x\$

Dividing on both sides by '\$ 5 \$' of the equality

\$ 9/5 = \cancel(5)/\cancel(5)x \$

After cancelation

\$ x = 9/5 \$

Answer

C = \$ x = 9/5\$
