2=y because you add one then divide by 2

First you want to put the variable in its own side so you’ll get 2y=4 since you have added one to each side cancelling the negative 1. Next 2y is twice as big is y so divide both sides by 2 and you’ll get y is equal to two

15/30 = n/34 round to the nearest tenth.
avanturin [10]
The equation given in the question has to be answered to the nearest tenth. The only thing that one should be careful about is the cross multiplication part. Other than that there is no difficulty in the given problem. Now let us get down to the equation in the question.
15/30 = n/34
30 * n = 15 * 34
30n = 510
n = 510/30
   = 51/3
   = 17
So the value of the unknown variable "n" comes out to be 17.
