Answer:

  • y = 7
  • x = -2

Explanation:

  • -4x + 3y = 29 __ equation 1
  • 5x + y = -3

<u>make x the subject in equation 2,</u>

5x + y = -3

y = -3 - 5x __ equation 2

<u>using substitution method,</u>

-4x + 3(-3 - 5x) = 29

-4x -9 -15x = 29

-19x = 38

x = -2

Find y,

y = -3 - 5x

y = -3 - 5(-2)
