alexandr1967 [171]

Answer:

7x² - 3x - 4

Step-by-step explanation:

Step 1: Write expression

(6x² - x + 3) + (-2x + x² - 7)

Step 2: Combine like terms (x²)

7x² - x + 3 - 2x - 7

Step 3: Combine like terms (x)

7x² - 3x + 3 - 7

Step 4: Combine like terms (constants)

3x - 3y = 9 and x + 3y = 12 Elimination

Firlakuza [10]

Answer:

$x=5.25,y=2.25$

Step-by-step explanation:

We can add the two equations to eliminate the variable $y$ and solve for $x$ :

$3x-3y+x+3y=9+12$

$4x=21$

$x=5.25$

Now, we can use substitution to solve for $y$ :

$x+3y=12$ (given)

$5.25+3y=12$

$3y=12-5.25$

$=6.75$

$y=2.25$

Hope this helps :)
