Answer:

x=-3, y=-19

Step-by-step explanation:

we can solve by substitution.

y = 2x-1 we can derive from the second equation.

plugging it into the first equation, 2x -3(2x-1) = 15.

simplying, 2x-6x+3 = 15 --> -4x+3 = 15, -4x = 12, x = -3.

now we know x, so we can solve for y by plugging it into one of the equations. --> -3*-6+y = -1

simplify, 18+y = -1 --> y = -19.

Answer:

Quotient: x+7

Remainder: -2

Step-by-step explanation:

Divide the terms (x² ÷ x =x)↓

(x² + 11x + 26) ÷ (x + 4) =x

Subtract x² + 4x (You have to the sign if each term)

(x² + 11x + 26) ÷ (x + 4) =x

-x² - 4x

-------------------

      7x + 26      

Divide the terms (7x ÷ x = 7)

x² + 11x + 26) ÷ (x + 4) =x + 7

Multiply the quotient by the dividend (x + 4) × 7 = 7x+28

(x² + 11x + 26) ÷ (x + 4) =x

-x² - 4x

-------------------

      7x + 26      

      7x + 28

------------------

           = -2 Remainder
