How do I solve for Y when the problem is 10x-5y=15 ?
2 answers:
Use the cover up method so cover up 10x so it looks like 5y=15 divide it then you have y so plug it in and solve for x hope this helps
10x - 5y = 15 :Cover up the 10x so -5y is left
-5y = 15 :Then, divide the whole equation by -5
<em><u>y = -3</u></em> (To figure out x, do the opposite and cover up the -5y)
