Solving for "y" means that we need to get y to be on one side of the equation. It should look like y= something. To get the y by itself, we need to get rid of that -3. To do that, we'll have to divide by -3 (because even though there's a y being divided, the -3 is still the numerator). 6/-3 is -1/2. Therefore your answer is y=-1/2

I used the 55.2 and the 0.6 to find a ratio of 92:1, so for every cm of toy car steering wheel there are 92 cm of real truck steering wheel. so using this ratio i times the 3.5cm of the toy car windshield by the 92, this gave me the answer of 322cm, which theoretically is the answer of this equation. 322cm.
