5y = 3x - 15

b3lla2025:

so 5y=0+15

b3lla2025:

@supie

supie:

Are we solving for x or y?

b3lla2025:

\(\color{#0cbb34}{\text{Originally Posted by}}\) @supie Are we solving for x or y? \(\color{#0cbb34}{\text{End of Quote}}\) y

supie:

Ok so the first step is to combine the like terms \(5y=(0+15)\) equals what?

supie:

solve what's inside the parenthesis

b3lla2025:

15

supie:

Yes so \(5y=15\) so you know the next step?

b3lla2025:

then divide both sides by 5 and y=3

supie:

Yes y=3

b3lla2025:

\(\color{#0cbb34}{\text{Originally Posted by}}\) @supie Yes y=3 \(\color{#0cbb34}{\text{End of Quote}}\) thxs

supie:

because 15/5=3

supie:

\(\color{#0cbb34}{\text{Originally Posted by}}\) @b3lla2025 \(\color{#0cbb34}{\text{Originally Posted by}}\) @supie Yes y=3 \(\color{#0cbb34}{\text{End of Quote}}\) thxs \(\color{#0cbb34}{\text{End of Quote}}\) np

b3lla2025:

so do I do this for all my math problems that I need to find y for

b3lla2025:

@supie

supie:

Well sometimes there is an extra step(s)

b3lla2025:

(y + 5) = 2/3(x - 7) how do you find the slope for this

supie:

\((y + 5) = 2/3(x - 7)\longrightarrow 2x-3y=29\)

supie:

So then just find the slope from that (y=mx+b) find m

b3lla2025:

so 3=2x+29

supie:

....no- you have to find m the slope (y=mx+b)

b3lla2025:

I'm confused

b3lla2025:

\(\color{#0cbb34}{\text{Originally Posted by}}\) @supie ....no- you have to find m the slope (y=mx+b) \(\color{#0cbb34}{\text{End of Quote}}\) sorry

b3lla2025:

m=-3/5

supie:

I dont think so-

b3lla2025:

\(\color{#0cbb34}{\text{Originally Posted by}}\) @supie I dont think so- \(\color{#0cbb34}{\text{End of Quote}}\) (y + 5) = 2/3(x - 7) what is the point? @supie

b3lla2025:

@Laylalyssa

b3lla2025:

help @supie

supie:

What do you need help with?

\(\color{#0cbb34}{\text{Originally Posted by}}\) @b3lla2025 @Laylalyssa \(\color{#0cbb34}{\text{End of Quote}}\) wuit?
