# Solve the following equation: 7x - 9 = 16

**Solution:**

An equation is a mathematical statement with an 'equal to' symbol between two algebraic expressions that have equal values. The two sides of an equation is always balanced.

We perform mathematical operations on the simple equation given so that the balance is not disturbed.

We know that while transposing any term from LHS to RHS or RHS to LHS, the sign of the term gets changed.

- + changes to -
- - changes to +
- × changes to ÷
- ÷ changes to ×

7x - 9 = 16

Transposing -9 to RHS, we get

7x = 16 + 9

⇒ 7x = 25

Now dividing both sides by 7, we get

x = 25/7

Therefore, x = 25/7
