Is it

or

?
both start out the same, just remember what you do to one side you have to do to the other, so subtract both sides by 1/4, then you want to get y alone, so either divide or multiply the 3 on both sides! let me know which it is and I can help you out more
[edit] it's the second, and not going to use cross multiplication.
added a picture that walks you through it :)
Answer:
x = 23
Step-by-step explanation:
These are supplementary angles so the sum of those angles add up to 180:
3x + 16 + 5x - 20 = 180
8x - 4 = 180
8x = 180 + 4
8x = 184
x = 184/8
x = 23
Given:
Width of a rectangle = 
Length of the rectangle = 
To find:
The ratio of the width to the length.
Solution:
We need to find the ratio of the width to the length.

Putting the given values, we get





Therefore, the ratio of the width to the length is 1:3.
Answer:
1.33
Step-by-step explanation:
62 can only be subtracted from 82 once. So 82.46-62 would be 20.46. Since you can't subtract anymore you put a decimal point. 62x3=186 and 20.46-186=1.86 and you can subtract 186-186=0.
Answer:
k = (p -8)/3
Step-by-step explanation:
To solve for k, we undo what is done to it.
p = 3k +8 . . . . . given
p -8 = 3k . . . . . . subtract the added constant
(p -8)/3 = k . . . . . divide by the multiplier
The desired expression is ...
k = (p -8)/3
