Answer:

x=-52

Step-by-step explanation:

multiple everything by 3 to get rid of the fractions

3(1/3x-2/3=-18)\\1x-2=-54\\

rewrite

x-2=-54

add 2 to both sides

x-2+2=-54+2\\x=-52

Answer:

x=-52

Step-by-step explanation:

\frac{1}{3} x-\frac{2}{3} =-18

Add \frac{2}{3} to both sides of the equation:

\frac{1}{3} x=-18 +\frac{2}{3}

Simplify -18+\frac{2}{3} by multiplying -18 in fraction form -\frac{18}{1} to get a common denominator so you can add the two fractions:

-\frac{18}{1} × \frac{3}{3}=-\frac{54}{3}

Now add the two fractions:

-\frac{54}{3} +\frac{2}{3} =-\frac{52}{3}

Now write the simplified equation:

\frac{1}{3} x=-\frac{52}{3}

Divide both sides of the equation by the coefficient of x, which is \frac{1}{3}:

x=-\frac{52}{3} ÷ \frac{1}{3}

Use the reciprocal of the dividend (\frac{1}{3}), and multiply by your divisor:

x=-\frac{52}{3} × \frac{3}{1}

x=-\frac{156}{3}

Simplify the fraction by dividing -156 into 3:

x=-52

Gekata [30.6K]

Note: "total" is from adding the first and last columns (middle column should be provided because it is a rate which cannot be added).

                       Amount        x        Cost             =         Amount x Cost

Cranberry:          q                        $6.30                          $6.30q

Apple:            <u>    4       </u>                  <u>$3.60</u>                      <u> $3.60(4)  = $14.40</u>

Total:                4 + q                     $4.50           =         $6.30q + $14.40

                                                   $4.50(4 + q)   =          $6.30q + $14.40

                                             $18.00 + $4.50q  =          $6.30q + $14.40

                                                              $3.60  =           $1.80q

                                                                    2    =           q

Since you didn't provide the equation options, hopefully you can use the solution to help you decide which option to choose.
