Solve the system by substitution. 3x-6y=2 4x+3y=-1

crimeas [40]

Answer:

y = -1/3

x = 0

Step-by-step explanation:

3x-6y = 2 then 3x = 2+6y, x=(2+6y)/3

4x+3y = -1

substitute for x

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

8/3+8y-6y = 2

reduce

2y = 2-8/3

2y = -2/3

divide both sides by 2

y = -1/3

4x+3(-1/3) = -1

4x = 0

x = 0

The selling price of an item is $600. After 6 months of not selling, it is marked down by 30% . After another 6 months of not se

Bingel [31]

The sale price after both markdowns will be $336

Explanation

The selling price of an item is $600. After 6 months of not selling, it is marked down by 30%

So, the marked down amount after 6 months $=\$ 600*0.30= \$180$

and the selling price after first 6 months will be: $\$600-\$180=\$420$

After another 6 months of not selling , it is further marked down by 20%. So, the marked down amount now $= \$420*0.20=\$84$

Thus, the final selling price after all markdowns $=\$420-\$84=\$336$
