Answer 2

Answer: 4x-3y=19,. Eq- 1

3x+3y=9​. Eq - 2

By Substitution Method

By Equation 1

4x = 19 + 3y

x= 19 + 3y /4

Substituting value of x in equation 2

3 ( 19+ 3y )./4 + 3y = 9

57+ 9y +12y / 4 = 9

57 + 21y = 9×4

21y = 36-57

y = - 21 / 21

y = -1

Putting value of y in equation 1

4x-3y=19

4x - 3× (-1) = 19

4x + 3 = 19

4x= 19 -3

4x = 16

x = 16/ 4

x= 4
