Answer:
(-9, -7)
Step-by-step explanation:
To solve this, i used the elimination method.
17x - 19y = -20
x + y = -16
multiply both sides by -17
and that will give you =
17x - 19y = -20
-17x - 17y =272
then i added the equations.
-36y = 252 (divide both sides by -36)
y = -7
now that you have found the y value, the next step is to find the x value and for that you need to pick an equation and solve it.
x + y = -16
x + (-7) = -16 (replace y with -7)
x = -9
(x,y) = (-9, -7)
<span>d = 5x + 5y
5y = d - 5x
y = (d - 5x) / 5</span>

Answer: 768</h3>
======================================================
Explanation:
To go from gallons to fluid ounces (abbreviation fl oz), we multiply by 128
For example, 2 gallons becomes 2*128 = 256 fl oz as shown in the table.
Another example: 3 gallons = 3*128 = 384 fl oz.
Therefore, 6 gallons would be 6*128 = <u>768</u> fl oz.
To go in reverse, from fl oz to gallons, we divide by 128.
Answer:
= -1/4x +3/7y+10
Step-by-step explanation:
3/7y=x/4+10=-1/4x+3/7y+10
<u>Answer:</u>
- x = 1
- New equation: 7 - 2 = 5
<u>Step-by-step explanation:</u>
- 7 - 2x = 5
- => 7 - 5 = 2x
- => 2 = 2x
- => x = 1
<u>Conclusion:</u>
Since:
Our new equation will be 7 - 2 = 5
Hoped this helped.
