Question

If the linear equation 4x = 10 − 5y is written in standard form, what is the value of B?

Answer 1

you need to isolate x, and b would be the only value that does not multiply x. If you divide everything by 5to let y alone, the only term that is not multipling x would be 5, but since y is negative, you need to multiply everything by -1, and you get B=-5

Answer 2

ahh!!
