Question

Please help me with this problem and can you write down the steps.

y-1
____
x+3 = 3/4 (equivalent ratio)

Answer 1

(y-1)/(x+3) = 3/4
4(y-1) = 3(x+3)
4y-4 = 3x+9
3x-4y+13 = 0

Not sure where you want to go with this.

Answer 2

Thank you Steve can you explain what your step are in the problem above you worked for me please.

Answer 3

all I did was clear the fractions, just as you would if you were doing, say,

x/2 = 3/7
7x = 3*2

After that, I just expanded terms and simplified. You never said what you wanted to do with the fractions. Naturally, if y=4 and x=1,

(y-1)/(x+3) = 3/4
