Using the expression 7x=3y, if y is 35 what is x

X is 15.

Here's the instructions on how to do it.

3y = 7x, so if y is 35, we'll have to turn y into 35, which should be (3) (35) = 7x. That equals 105. Now that we got 105, we know that 105 = 7x. Next up, divide 7 by both sides, that's 15 = x.

The answer is 15, 3•35=105 divide 105 by7 and you have your answer
