\huge\fcolorbox{blue}{aqua}{Answer:}

═════════════════════

1.- 5x - y = 8

<h3>Solve for x</h3>

-5x-y=8

-5x=8+y

-5x=y+8

\frac{-5x}{-5}=\frac{y+8}{-5}

x=\frac{y+8}{-5}

x=\frac{-y-8}{5}

<h3>Solve for y</h3>

-5x-y=8

-y=8+5x

-y=5x+8

\frac{-y}{-1}=\frac{5x+8}{-1}

y=\frac{5x+8}{-1}

y=-5x-8

────────────────────

2.-4x-y=2

<h3>Solve for x</h3>

-4x-y=2

-4x=2+y

-4x=y+2

\frac{-4x}{-4}=\frac{y+2}{-4}

x=\frac{y+2}{-4}

x=-\frac{y}{4}-\frac{1}{2}

<h3>Solve for y</h3>

-4x-y=2

-y=2+4x

-y=4x+2

\frac{-y}{-1}=\frac{4x+2}{-1}

y=\frac{4x+2}{-1}

y=-4x-2

5 &lt; 4x = 2&gt; 3x PLEASE HELP
Galina-37 [17]
Looks fishy to me, the way this problem combines <, = and > symbols.

But anyway.  Subtract 3x from both sides.  You'll get

5 < x = 2 > 0      2 > 0 is true, but that's a different type of math problem (true or false).    If you decide to substitute '1' for 2 > 0, then the "1" says "TRUE."

Then 5 < x = true, so you must find x values that are larger than 5.

That would be (5, infinity)

Please go back and ensure that you have copied down the original problem exactly as it appears.

You recycled a total of 30 cans and bottles and made $1.80. For cans you get $0.05 and for bottles
Svetlanka [38]

Answer:

27

Step-by-step explanation:

x + y = 30

0.05x + 0.15y = 1.80

x = 30 - y

1.5 - 0.05y + 0.15y = 1.80

0.10y = 0.30

y = 3 (bottles)

x = 27 (cans)
