GivEn:

  • 2x - 3y + 8 = 0
  • 3x + y + 1 = 0

To find:

  • The value of x and y?

Solution:

• Firstly, Let's find out the value of x by solving the first equation.

⠀⠀━━━━━━━━━━━━━━━━━━━━━━━━━━━━━⠀

« Finding the value of x,

→ 2x - 3y + 8 = 0

→ 2x - 3y = -8

→ 2x = - 8 + 3y

→ x = 3y - 8/2

⠀⠀━━━━━━━━━━━━━━━━━━━━━━━━━━━━━⠀

« Finding the value of y by substituting the value of x in eq 2,

→ 3x + y + 1 = 0

→ 3(3y - 8/2) + y + 1 = 0

→ 3(3y - 8/2) + y = -1

→ 9y - 24/2 + y/1 = -1

→ 9y - 24/2 + 2y = -1

→ 9y - 24 + 2y = -1 × 2

→ 11y - 24 = -2

→ 11y = -2 + 24

→ 11y = 22

→ y = 22/11

→ y = 2

⠀⠀━━━━━━━━━━━━━━━━━━━━━━━━━━━━

« Finding the value of x by substituting the value of y in eq 1,

→ 2x - 3y + 8 = 0

→ 2x - 3(2) + 8 = 0

→ 2x - 6 + 8 = 0

→ 2x + 2 = 0

→ 2x = -2

→ x = -2/2

→ x = -1

∴ Hence, The value of y is 2 and the value of x is -1.
