Algebra question? Easy ten points?

I really don’t understand these! I would be grateful if someone could explain to me how to do these three problems (they are quesions on a studyguide). My test is on Tuesday, and I don’t understand it… Any help is appreciated! Thanks!

a.) 3x – 4 = 2y – 2

b.) 8 = 2/3xyz

c.) m/3 + 6 = n/2

I think it’s the variables that confuse me the most… Thanks.

a) Step1 [add 2]: 3x-2=2y

Step2 [divide by 2]: (3x-2)/2=y

b) Step1[divide each side by 2/3]: 12=xyz

Step2 [now divide by xz]: 12/xz=y

c) I didn’t know what variable you are solving for since there’s no y so sorry, I solved for both n&m.

Step1 [multiply by 2]: 2m/3 + 12 = n

if solving for m…

Step1 [subtract 6 from both sides]: m/3 = n/2 – 6

Step2 [multiply by 3]: m = 3n/2 – 18

a) you have to get y alone so first you have to add 2 to both sides then you have to divide both sides by 2.

3x – 4 = 2y – 2

+2 +2

———————

3x – 4 + 2 = 2y <-doing that it cancels out the 2 on the right ------------- ---- 2 2 3x - 4 + 2 = y ------------- 2 b) You have to divide both sides by 2/3xz to get y by itself and since you can't have a fraction in a fraction you have get rid of 2/3 by multiplying my 3/2 8 = 2/3xyz --- --------- 2/3xz 2/3xz 8 = y --- 2/3xz (3/2) * 8 ------------ = y 2/3xz 12 ----- = y xz c) m n --- + 6 + --- (what are solving for?) 3 2

a) 3x-4=2y-2

3x-4+2=2y

(3x+6)/2=y

b) 8=2/3xyz

12.0012=xyz

(12.0012)/x=yz

((12.0012/x)/z)

c) m/3+6=n/2

2(m/3 +6)=n
