Step-by-step explanation:
*Whatever you do to one side of the equal sign you must do to the other!
- Move the (coefficients?) to one side of the equal sign
2. Get rid of the constant(Notice the negative sign beside the 18. This means you add to get to 0)
3. Separate the number from the variable by dividing because 4x= 4 times x. You must do the inverse operation to get rid of the 4. (Inverse of addition is subtraction, Inverse of subtraction is addition, Divisions multiplication and multiplications division)
Since 4 doesn't go into 30 evenly, I chose to keep it as an improper fraction. If you'd prefer mixed number: 7 2/30
Sorry if it's confusing! Hope I helped! :)
