Solve for y: 7/9y = 42

7/9y=42

Take the denominator and multiply it by the whole. 9*42=378

Then take your answer and divide it by the numerator. 378/7=54

To check your work just simply multiply 7/9 * 54 = 42

I answered on paper hope that is alright with you. I just find it easier for math problems. That slash means two numbers cancel each other out. What's in the box is the answer and the proof that it's right is underneath.
