Answer:
4x-y=18
Step-by-step explanation:Since x is on the right side of the equation, switch the sides so it is on the left side of the equation.
4 x − 18 = y
Move y to the left side of the equation because it contains a variable.
4 x − 18 − y = 0
Move 18 to the right side of the equation because it does not contain a variable.
4 x − y = 18
