Step-by-step explanation:

$(e + 3)(e - 5) \\ e \times e + e \times ( - 5) + e \times e + e \times 3 \\ { e}^{2} + ( - 5e) + {e}^{2} + 3e \\ {2e}^{2} + ( - 2e)$

In this type of math equation, you have to multiply all members from the first part with the second part.

Expanded:

$e \times e+e \times (-5)+e \times e+e \times 3$

simplified:

${2e}^{2} + ( - 2e)$

X - Phones.
Y - Phone accessories. $ = 10x + 4y.

If she sold 7 phones, she would have to sell 14 accessories. 126 = 10(7) + 4(14). 70 + 56 = 126.
