I need to step-by- step ways on how this is or isn’t a solvable equation. Please HELP

it is a solvable equation

Step-by-step explanation:

(x + 2) -3(x - 4) = 6 and x = 4

if x = 4 then fill in all the x's with 4 so the equation is now:

(4 + 2) -3(4 - 4) = 6

Use PEMDAS

Now the equation is 6 - 3(0) = 6

-3 times 0 is 0 so it's 6-0=6

6 = 6

when you put the 4 in for the x variables and the numbers on both sides of the equal sign are the same it makes the equation true

hope this makes sense and hope it helps :)

use an equation of ratios to determine the amount of gas needed to fill the tank.

    0.2             0.8

  =    

288.75             x

                                                              231 gal

so, 0.2x = (0.8)(288.75 gal), and x = = 1155 gal.

                                                                0.2

it would take 1155 gal. to fill the tank.

the cost would be

1155 gal         $3

* = $3465   (answer)

      1           1 gal

hope this you

the answer to the expression is 83
