Question

Find the value of x and y. y=2x and 1.85x+3.7y=12.95

Answer 1

x=1.4 y=2.8

Explanation:

Lets substitute y with 2x. We get: 1.85x+7.4x=12.95.

Simplifying by combining x: 9.25x=12.95

Then you just divide 12.95 by 9.25: x=1.4

Now for y. We know why is 2x so we just have to multiply x by 2: y=2x, y=2.8.
