sesenic [268]

Answer:

x=2.7142 y=-2.8571,

Step-by-step explanation:

given 4x-8y=12............(1)

14+2x=-6y

2x+6y=-14..........(2)

from equ (2) multiply by 2

4x+12y=-28............(3)

substruct (1) and (3)

4x-8y-4x-6y=12-(-28)

-14y=40 ,y= $\frac{40}{-14}$ =-2.8571

y=-2.8571 put in equ (1)

4x-8(-2.8571)=12

4x=12-22.857=10.8571

x= $\frac{10.8571}{4}$

x=2.7142

Alexus [3.1K]

The answer is 244.80

You can calculate this by taking 36.72 and dividing it by 0.15 (15%). You would do this because it is the opposite of multiplying an original number by 0.15 (15%) to get 36.72.
