Help!!! Quick!!! Plzzzzz!!!

Answer:

x = -8

y = 9

Step-by-step explanation:

to solve this expression using simultaneous equation, we would say let

y =9............................................. equation 1

 6x + 5y =-3............................................equation 2

substitute equation 1 into equation 2

-3 = 6x + 5y............................................equation 2

6x + 5(9) = -3

6x + 45 = -3

collect the like terms

6x = -3-45

6x = -48

divide both sides by the coefficient of x which is 6

6x/6 = -48/6

x = -8

therefore y = 9

x = -8

  • Width: w = 3x(−2y)

<u>Perimeter of rectangle</u>

  • P = 2(l + w)

<u>Using the given values</u>

  • P = 2( 4- 7(3x + 4y) + 3x(-2y)) =
