To solve a proportion, you can either use cross products or basic multiplication.
To do cross products, you would multiply 17 (1st numerator) by 6 (2nd denominator).
Do the same with the other diagonal angle, 3 times y.
You'll end up with 3y = 102.
To solve for y, you divide both sides by 3.
102 ÷ 3 = 34
y = 34
The other way you could solve this is to see that 6 is 2 times as large as 3, so you would multiply 17 by 2 to get an equal proportion.
3 × 2 = 6
17 × 2 = 34
Your final answer is y = 34. Hope this helps! :)
Answer:
X = 9/2 or X = 3
Step-by-step explanation:
5x + 2 = 7x -7
5x - 7x = - 2 - 7

2 2
X = - 9/2
or X = 3 (lowest term)

-2
the second equation is the result of subtracting 2
The sum of 107+0(which has no value so it's like it's not even there) +39+13 = 159
