3m + 2n= p solve for n

subtract 3m on both sides
2n = p - 3m

divide both sides by 2
n = p/2 - 3m/2
-----------------------

xy - 5 = k solve for x
add 5 on both sides
xy = k + 5

divide both sides by y
x = k/y - 5/y

Answer:

Nina would have total expenses and sales $156 after selling 4 necklaces.

Step-by-step explanation:

Let <em>x</em> represent the amount of necklaces made and sold.

The initial cost was $140 and it costs $4 to produce one necklace. Hence, the total cost after producing <em>x</em> necklaces can be represented as:

\displaystyle 140 + 4x

Each necklace sells for $39. Hence, the total profit after selling <em>x</em> necklaces can be represented as:

\displaystyle 39x

To break even, the total cost and profit must be equivalent. Hence:

\displaystyle 140 + 4x = 39x

Solve for <em>x: </em>

<em />\displaystyle \begin{aligned} 140 + 4x & = 39x \\ \\ 140 & = 35x \\ \\ x & = 4 \end{aligned}<em />

<em />

Hence, the break even, Nina would need to sell four necklaces.

And the total expenses/profit would be:

\displaystyle \$39(4) = \$156

In conclusion, Nina would have total expenses and sales $156 after selling 4 necklaces.
