frozen [14]

Hey there, if you want to know the tax of 40 dollars. The answer is going too be 43.20. Or if you want to know just the tax its going to be 3.20.

The way i did this was to multiply 40 times 8 since each tax is 8 cents.

4x - 3y = -28<br>x + 5y = 39 cant seem to be able to figure the answer for this

Rus_ich [418]

value of x = -1 and value of y=8

Step-by-step explanation:

We need to solve the system of equations:

$4x - 3y = -28\,\,\,(1)\\x + 5y = 39\,\,\,(2)$

Multiply eq(2) with 4 and subtract with eq(1)

$4x-3y=-28\\4x+20y=156\\-\,\,\,-\,\,\,\,\,\,\,\,\,\,\,\,\,\,-\\--------\\-23y=-184\\y=\frac{-184}{-23}\\y=8$

So, value of y=8

Now, finding value of x by putting value of y in equation 2

$x+5y=39\\x+5(8)=39\\x+40=39\\x=39-40\\x=-1$

So, value of x = -1

value of x = -1 and value of y=8
