3 0

Answer:

1 solution

Step-by-step explanation:

3(2x-7)=9

dustribute: (3)(2)+(3)(-7x)=9

6+-21x=9

subtract 6 from both sides: -21x=3

Divide both sides by -21: x=-1/7

so your 1 solution is x = - 1/7

-6+14 =12-8x what is x<br><br><br> Show steps please
Leona [35]
<span>-6+14 =12-8x


-6+14 = 8

then

8 = 12 - 8x            -12

8-12 = 12 - 12 -8x


8-12 = -4
and
12-12=0


then
-4 = -8x      /-8

-4/-8 = -8x/-8

-4/-8 = 1/2

then

1/2 = x

so that: x = 1/2 = 0.5


hope that helps

A rectangular prism with a length of 7 inches, a width of 3 inches, and a height of 1 1/2  inches.
