Question

How do I solve for Y when the problem is 10x-5y=15 ?

Answer 1

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

Answer 2

10x - 5y = 15       :Cover up the 10x so -5y is left

-5y = 15              :Then, divide the whole equation by -5

y = -3                 (To figure out x, do the opposite and cover up the -5y)
