−3x − 3y = 3

y = −5x − 17

solve the above system of equations using substitution. show all work.

. i have the flu and my brain isn't working.

  (x, y) = (-4, 3)

Step-by-step explanation:

I would start by dividing the first equation by 3 (because you can).

  -x -y = 1

Now, substitute the expression in the second equation for y:

  -x -(-5x -17) = 1

  -x +5x +17 = 1 . . . . . use the distributive property to eliminate parentheses

  4x = -16 . . . . . . . . . . collect terms, subtract 17

  x = -4 . . . . . . . . . . . . divide by 4

  y = -5(-4) -17 = 20 -17 = 3 . . . . . substitute for x in the second equation

The solution is (x, y) = (-4, 3).

600,000,000,000, or 6e14

step-by-step explanation:

answer:   x*94 +688*6   = 267*100

94x+4128=26700    

94x=22572     /94

x=240.128
