The point of this equation is to figure out the value of the y variable. to do this, you'll need to get the y variable by itself on one side of the equation.
so first you would add 6.9 to 3.18. the equation would now look like this: 4.8y=10.08
you would then divide 4.8 by 10.08. this is the last step to getting the y varible by itself on one side of the equation and ultimately the value of y! the equation now looks like this: y=2.1
