Solve the system of equations Please If you could solve this it would honestly mean so much! Thank you!
Kay [80]

Answer:

(2, 8)

Step-by-step explanation:

There are a couple of different ways to do this, but I am going to use substitution since we already have one of those equations solved for y.  If y=3x+2, then we can sub 3x+2 in for y in the other equation:

-3x + 2(3x + 2) = 10 and

-3x + 6x + 4 = 10 and

3x + 4 = 10 and

3x = 6 so

x = 2.  Now that we know x = 2, we can sub a 2 in for x in either equation to solve for y:

y = 3x + 2 gives us, with the substitution, y = 3(2) + 2 so y = 8.  The solution set is (2, 8)

Aloiza [94]

Answer:

<h2>x{}^{2} - x - 6</h2><h2 />

Step-by-step explanation:

(x + 2)(x - 3)

Multiply each term in the first parentheses by each term in the second parentheses ( FOIL)

x(x - 3) + 2(x - 3)

Calculate the product

{x}^{2}  - 3x + 2x - 6

Collect like terms

{x}^{2}  - x - 6

Hope this helps..

Best regards!
