Answer 1

Answer:

HEY BUD MARK ME AS THE BRAINLIEST !

Step-by-step explanation:

2x + 3y = 11 ----(1) x-2y = -12 ----(2) (2) ⇒ x = 2y -12 ----(3) Substitute value of x from (3) in (1), we get 2(2y -12) +3y = 11 ⇒ 4y – 24 + 3 y = 11 ⇒7y = 35 ⇒y = 5  Substituting value of y = 5 in equation (3), we get x= 2(5) - 12 = 10 - 12 = -2 Hence x = -2, y=5 is the required solution  Now 5= -2m +3 ⇒2m = 3-5 ⇒2m = -2 m = -1
