Can you help explain so I know how to it do in case I get another similar question like this?

the basic rule is just to get x by itself start with Equation 1: 3/4 (x − 12)=12 distribute the (3/4) (3/4)(x-12) = ?

uh not quite...

meaning that A = 3/4, B = x, C = 12 now find A*B - A*C
anonymous
  • anonymous
so 3/4 * x and 3/4 *12
Vocaloid
  • Vocaloid
yes that gives us (3/4)x- 9 now we have (3/4)x - 9 = 12 now solve for x
anonymous
  • anonymous
o:
Vocaloid
  • Vocaloid
(3/4)x - 9 = 12 add 9 to both sides
anonymous
  • anonymous
to 3/4 and 9?
Vocaloid
  • Vocaloid
no, you can't add 9 to (3/4) since (3/4) is attached to x
Vocaloid
  • Vocaloid
(3/4)x - 9 + 9 = ?
anonymous
  • anonymous
(3/4)x - 18 = 12
Vocaloid
  • Vocaloid
nope -9 + 9 = ?
anonymous

0
Vocaloid
  • Vocaloid
good. so what is (3/4)x - 9 + 9 ?
anonymous
  • anonymous
(3/4)x = 12??
Vocaloid
  • Vocaloid
almost you also need to add 9 to the right side
Vocaloid
  • Vocaloid
(3/4)x - 9 = 12 becomes (3/4)x = 12 + 9 = 21 with me so far?
anonymous
  • anonymous
yes
Vocaloid
  • Vocaloid
good (3/4)x = 21 now solve for x
anonymous
  • anonymous
28
Vocaloid
  • Vocaloid
good. so x = 28 ready for equation 2?
anonymous
  • anonymous
Thank you and yes
Vocaloid
  • Vocaloid
3/4 y − 12=12 again, we want to get y by itself start by adding 12 to both sides
anonymous
  • anonymous
3/4 y - 12 + 12
anonymous
  • anonymous
so um 3/4 y - 12 = 12
anonymous
  • anonymous
@Vocaloid am i right or am i speaking nonsense?
Vocaloid
  • Vocaloid
not quite (3/4)y - 12 + 12 = ??
anonymous
  • anonymous
sorry @Vocaloid connection is bad right now but i fixed it um (3/4)y - 12??
anonymous
  • anonymous
am i right? sorry for bothering you i just need help @Vocaloid
Vocaloid
  • Vocaloid
the - 12 and the 12 cancel out... (3/4)y - 12 + 12 = 12 + 12 (3/4)y = 24 solve for y
anonymous
  • anonymous
32 @Vocaloid

  • Vocaloid
good
