1 answer:
Leona [35]2 years ago

Answer:

\sf C)  \  x = -1\dfrac{2}{5}  , \  y =  \ 1\dfrac{3}{5}

Given equations:

  • a) -3x + 3y = 9
  • b) 2x - 7y = -14

<u>Make x the subject in equation 1</u>:

  • -3x + 3y = 9
  • -3x = 9 - 3y
  • x = y - 3

<u>Substitute this into equation 2</u>:

2(y - 3) - 7y = -14

2y - 7y = -14 + 6

-5y = -8

  y = -8/-5

  y = 1.6

Then x = y - 3

           = 1.6 - 3

           = -1.4

Solution: (x, y) ⇒ (-1.4, 1.6)
