4(2x3)-3x=5(x-2)+3 how do you do this?

First of all, we have to expand the brackets.

8 x 12 - 3x = 5x - 10 + 3

Then, we have to put all the x terms on one side. We do that by adding 3x to both sides to get rid of that -3x on the left.

8 x 12 = 8x - 10 + 3

Now we have to get x on its own, so if we do the numbers first to make it easier:

96 = 8x - 7

Now add seven to both sides: 103 = 8x

Then divide both sides by eight to find x. This leaves us with 12.875.

Hope I helped!

25/4

step-by-step explanation:

call segment cd's length x. because dc and ab are parallel, angle acd and cab, so triangles adc and abc are similar and we can set up the equation x / ac = ac / ab, or x / 5 = 5 / 4 and x = 25/4.

x = 17

step-by-step explanation:

1st step: isolate x.

24 - 3x = -27

-24         -24

-3x   =   -51

2nd step: divide.

-3x     =   -51

  3             3

  x       =     17

hope this
