Anyone good with Algebra??
What is the "X" intercept of 4y12=28x?I found the "Y" intercept... no problem. I see the 28x and I'm not sure how to get rid of the 28 and still keep both sides equal. I'm sure I'd have to divide since "28x" is multiplication... I'm just not sure where to go from there. Solve and explain, pleassssssse.

to find y intercept, you take x = 0then 4y  12 = 04y = 12y = 3to find x intercept, simply set y=012 = 28xx = 12/28x = 3/7

x= (4y12) /28 or (y3)/7

the first thing to do is find Ythen take 28 and divide it by 4the # that was 28 divide it form both sidesthen take the # that is now Y and subtract it from both sides then add 12 to both sides because it is a negativeYou should now have your answer X
