Question 207050This question is from textbook Elementary and intermediate algebra
: I am to solve for y. eg y-x=3 so y=x+3
a. (y-1)/(x+3)=3/4
This is what I have done so far:
y-1=3/4 x (x+3)
y-1=3x/4 + 9/4 + 1
y=3x/4 + 9/4 +1
From here, I am lost. Also I have to solve
b. (y-h)/(x+k)=a
This is what I have so far:
(y-h)=a x (x+k)
(y-h)= ax + ak
Again, from here I am lost. Help!!

Solve for y:
a. %28y-1%29%2F%28x%2B3%29+=+3%2F4 Multiply both sides by (x+3), as you have done!
y-1+=+%283%2F4%29%2A%28x%2B3%29 Now add 1 to both sides.
y+=+%283%2F4%29%2A%28x%2B3%29%2B1 This can be simplified to:
y+=+%28%283x%2B9%29%2F4%29%2B1 or, if you multiply the second term on the right side by 4%2F4 and then add the two fractions, you get...
y+=+%283x%2B9%2B4%29%2F4 or...
highlight%28y+=+%283x%2B13%29%2F4%29
b. %28y-h%29%2F%28x%2Bk%29+=+a Multiply both sides by %28x%2Bk%29
y-h+=+a%28x%2Bk%29 Now add h to both sides.
y+=+a%28x%2Bk%29%2Bh Which simplifies to...
y+=+highlight%28ax%2Bak%2Bh%29
