x =

# 5/4 #

#### Explanation:

Add 1 to both sides of the equation. This will 'isolate' x-term.

so 4x - 1 + 1 = 4 + 1

and 4x = 5

(divide both sides by 4 )

#(cancel(4) x)/cancel(4) = 5/4 # so x =

# 5/4 # Note: An equation is like a 'balance' about the '=' sign.

[So whatever 'operation' you carry out must be carried out on

both sides of the equation to 'maintain' the balance.]
