Question

3x − 2y = 15
y = 2x − 11



what is the solution

Answer 1

=3 x - 2y = 15

= 3x - 2(2x - 11) = 15

=3x - 4x + 22 = 15

= -x + 22 = 15

= x = 22 - 15

= x = 7

hope it help you

Answer 2

3x - 2y = 15 -------- equation 1

y = 2x - 11 -------- equation 2 putting the value of equations 2 in 1

3x - 2(2x - 11) =15

3x -4x + 22 = 15

-x = 15 - 22

- x = -7

x = 7

putting the value of x in equation 2

y = 2 × 7 - 11

y = 14 - 11

y = 3

x = 7 , y = 3
