4y - 3(y + 8) = 12?

Answer 1

4y - 3(y + 8) = 12
4y -3y - 24 = 12
y -24 =12
y = 36

Answer 2

I do like the y = 36 answer however if your interested in a bit of lateral thinking:

4y -3(y + 8) = 12?
then
4y -3y -3x8 = 12?
so
y - 24 = 12?
hence
y = 12? + 24

There's your function where ? is a parameter or another function! As you can see no matter the size of the value of ?, y is relatively big, eg
if ? = 1, then y =36
Aint that noice!

Answer 3

First: use distribution to eliminate the parenthesis > multiply 3 by both terms in the parenthesis >

4y - 3(y) - 3(8) = 12
4y - 3y - 24 = 12

Sec: combine "like" terms > combine coefficients with the same variable >

y - 24 = 12

Third: solve for "y" and keep it on one side > add 24 to both sides (opposite side means opposite sign) >

y - 24 + 24 = 12 + 24
y = 36

Answer 4

4y - 3(y + 8) = 12
4y - 3y - 24 = 12
y = 36

Answer 5

4y-3y-24=12
+24 +24

y=36

Answer 6

4y - 3(y + 8) = 12
4y-3y+24=12---you do 3 x the y and 3x 8
then add the y values together 1y+24= 12
then subtract 24 from the 12 1y+24=12
-24 -24
to then equal 1y=-12
then divide by one /1 /1
and your final answer is y=-12 because negative divided by posative is still negative

hope that helps

Answer 7

4y-3y-3*8=12
y-24=12
y=12+24
y=36

Answer 8

4y-3(y+8)=12
4y-3y-24=12
y-24=12
y=36

Answer 9

y=36

Answer 10

4y-3y-24=12
y-24=12
y=36
