    n is being multiplied by 2 and then 7/3 is being subtracted. First, you must add 7/3 to both sides.

    8.6 is right because you do \[26 \div 3\]

    Now that we have 2n, and we want n, we divide both sides by 2. Dividing by 2 is the same as multiplying by 1/2

    i would like to offer an alternative mult whole equation by 3 3(2n-7/3=15) and you end up with 6n - 7 =45 add 7 to both and then divide both by 6 n=52/6 n=8.67
