Answer:

<u>Hence final answer is B: Step 2.</u>

Step-by-step explanation:

Step 1: Find the total points needed to score in six games: 96x6=576

Justification:

Product of 96 and 6 is 576 which is same number found by Brenda. So step 1 is correct.

Step 2: Find the total points scored: 92+110+85+78=365

Justification:

Sum of total points scored by Brenda is 92+110+85+78= 461.

But she got different value 365.

Hence step 2 is wrong.

<u>Hence final answer is B: Step 2.</u>

-5x-y= 8<br> -4x+y=2 solve the system

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

═════════════════════

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>

$-4x-y=2$

$-y=2+4x$

$-y=4x+2$

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

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

$y=-4x-2$
