density = 357.75 / 225 = 1.59 grams / milliliter
density = 1,590 grams / liter
Answer:
(x, y) = (5, 1)
Step-by-step explanation:
To <em>eliminate</em> x, you can double the second equation and subtract the first.
... 2(x +4y) -(2x -3y) = 2(9) -(7)
...11y = 11 . . . . . simplify
... y = 1 . . . . . . divide by 11
Using the second equation to find x, we have ...
... x + 4·1 = 9
... x = 5 . . . . . subtract 4
_____
<u>Check</u>
2·5 -3·1 = 10 -3 = 7 . . . . agrees with the first equation
(Since we used the second equation to find x, we know it will check.)
Answer:
x=6
Step-by-step explanation:
Solve for x.
5x-15 = 2x+3
(Move the 2x to the other side of the equation.)
3x-15= 3
(Move the 15 to the right side of the equation.)
3x=18
(Divide both sides by 3 to isolate the variable.)
x=6
