Answer for brainliest asap

V125BC [204]

Answer:

$x = 8 \\ y = 9$

Step-by-step explanation:

$2y = x + 10 \\ y = 2x - 7 \\$

since they gave us a value for y in the second equation, we can input it into the first equation. so...

$2(2x - 7) = x + 10 \\ 4x - 14 = x + 10 \\ 4x - x = 10 + 14 \\ 3x = 24$

$\frac{3}{3} x = \frac{24}{3} \\ x = 8$

Since x is 8 we can find y by substituting 8 for x

$y = 2x - 7 \\ y = 2(8) - 7 \\ y = 16 - 7 \\ y = 9$

160 grams of zinc. 760/ 19 is equal to 40 so then we’d want to multiple 4 x 40 because that’s how much were growing by so then zinc is 160 grams
