Y=65
X=5
X=12
Y=?
65—->5
?——>12
Cross multiply
Y= (65x12) / 5
Y= 780 / 5
Y= 156
To check add the Y value in and remove an X value
65——> ?
156 ——> 12
Cross multiply
X= (12x65) / 156
X= 780 / 156
X= 5
You got the right answer. Hope this helped.
If the expression is 2*x*3, x must be 1/3 in order to cancel out the 3 which would leave the 2.
LABC is a 30°angle point B is at (3,2)
X² + x + ...m
x² + x + 1/4
\/x² = x
\/(1/4) = 1/2
2*x*1/2 = 2x/2 = x
x² + x/2 + 1/4
