Please help me find this (the answers for both X& Y should be integer), the answers are 9& 3 but I don't know the procedure to find them.
I really need this to learn so please give me the algorithm to solve such problems except trial and error if there is any or in case just by trial and error how to find the best guess for start point near final answers.
Thanks

Question 826686: I am trying to change this into slope-intercept form. The equation is 2x + 5y = 12. I divided by 2 first which turns the equation x + 5y = 6. I then divided 5 on both sides and turned the equation to x + y = 6/5. I then multiplied x on both sides and got y = 6/5x. Our teacher tiled us that we don't have to graph if b/y-intercept is a fraction. Did I solve this equation correctly?

Question 5703: Solve for r: 4(r-2)= 2(r+8)
This is how I am trying to do it:
I isolated the variable r
I multiplied the the terms
left side first, then right side and got:
4r-8 = 2r+16
Then I isolate r by subtracting both sides by 2 and got:
2r-8 = r+16
Then I isolated r by adding both sides by 2
4r-8 = r+16
Then I isolate r by dividing both sides by 2
2r-8 = 1r+16
Ultimately I got 4
and I seemed to got lost in the equation, please help :(
