**Solving exponential equations**

Solving exponential equations where a substitution is needed and exponential simultaneous equations.

Examples:

1. Solve the equation

2^{x} + 2^{1-x} = 3

2. Solve the simultaneous equations

3^{x} × 9^{y} = 1

2^{2x} × 4^{y} = 1/8

**How to solve simultaneous equations that use logarithms?**

Example:

Solve the simultaneous equations

log_{3}x + log_{3}y = 2

log_{3}(2y - 3) - 2log_{9}x = 1
