Plz help me plz hurry What is the solution to the system of equations?

7 x minus 2 y = negative 24. 5 x + 5 y = 15.

x=-2   y=5

Step-by-step explanation:

7x-2y=-24

5x+5y=15

35x-10y=-120

10x+10y=30

45x=-90

x=-2

-10+5y=15

5y=25

y=5

answer is 8x+24

area of vanessa's patio = length × width

given, length = (3x² + 5x + 10)

width = (x² - 3x - 1)

area of vanessa's patio = (3x² + 5x + 10)(x² - 3x - 1)

= 3x²(x² - 3x - 1) + 5x(x² - 3x - 1) + 10(x² - 3x - 1)

= 3x⁴ - 9x³ - 3x² + 5x³ - 15x² - 5x + 10x² - 30x - 10

= 3x⁴ - 4x³ - 8x² - 35x - 10

hence, expression of vanessa's patio = (3x⁴ - 4x³ - 8x² - 35x - 10)

49/6 is going to equal 8 1/6
