You would plug in y into the other equation.
-4x = x-5
Put x variables on one side
-4x - x = -5
-5x = -5
x=1
Then plug in 1 for x in any equation
y = 1 - 5
y = -4
So the answers are x=1 and y=-4
Hope this helped!

Jewelry marked 18- karat gold is 75% pure gold. How much pure gold is in an 18-karat gold necklace that weighs 258 grams

mihalych1998 [28]

Answer:

The weight of pure gold in 258 g rams of 18- karat gold is 193.5 grams.

Step-by-step explanation:

The pure percentage in the gold = 75%

The weight of the gold purchased = 258 g

Now, here the pure gold percentage is 75% of 258 g

75% of 258 grams = $\frac{75}{100} \times 258$

or, $\frac{3}{4} \times 258 = 193.5$

⇒75% of 258 grams = 193.5 grams

Hence, the weight of pure gold in 258 g rams of 18- karat gold is 193.5 grams.
