Solve for one of the variables from one equation. Substitute this into the other equation. Solve for the single variable in this equation. Use the value to solve for the other variable.



Like Do This:
x%28%2860%2F%28x%2B2%29%29%2B2%29=100

Reread what is discussed and try to see how the complex equation conforms to that discussion. Solve for x. You CAN do and understand this.
