Steps for finding the solution

We have 7x - 9 = 16

First, we move the non x terms to the RHS of the equation. To do this, we add 9 to both sides.

Note: if a = b, then a + c = b + c

Therefore, 7x - 9 + 9 = 16 + 9

or, 7x = 25

Next, divide both sides by 7, which is the coefficent of x

Note: if a = b, then a ÷ c = b ÷ c

7x/7 = 25/7

x = 25/7 or, x = 3.57
