A variable is a symbol for a number we don't know yet. it is usually
y a letter like x or y.
A number on it's own is called constant.
A coefficient is a number used to multiply a variable.
An operator is symbol that represents an operation.
Step 1 : Subtract both sides by 4 .
Step 2 : Simplify. 4-4 = 0 on the left and 14 - 4 = 10 on the right. then we need to think about how to remove the coefficient 2.
Step 3: Since the opposite of multiplication is division. I'm going to divide both sides by 2. simplify . 2/2 = 1 on the left. 10/2 = 5 on the right so the answer is x = 5.
