Answer:

$28x+8y+2$

Step-by-step explanation:

$-2\left(3x+12y-5-17x-16y+4\right) -> =-2\left(-14x-4y-1\right)$

$\mathrm{Distribute\:parentheses}$

$=\left(-2\right)\left(-14x\right)+\left(-2\right)\left(-4y\right)+\left(-2\right)\left(-1\right)$

$\mathrm{Apply\:minus-plus\:rules}\\\left(-a\right)\left(-b\right)=ab\\=2\cdot \:14x+2\cdot \:4y+2\cdot \:1\\=28x+8y+2$

during a sale at the local department store, you buy three sweatshirts and two pairs of sweatpants for $85.50. later you return

Alexxandr [17]

3s + 2p = 85.50....multiply by -1
3s + 4p = 123
--------------------
-3s - 2p = -85.50 (result of multiplying by -1)
3s + 4p = 123
--------------------add
2p = 37.50
p = 37.50/2
p = 18.75 <=== cost of the pants

3s + 4p = 123
3s + 4(18.75) = 123
3s + 75 = 123
3s = 123 - 75
3s = 48
s = 48/3
s = 16 <=== cost of each shirt
