Answer:
Solving by elimination method.
Multiply 2x - 3y =9 by 3 and multiply 3x - 2y =6 by 2.
6x - 9y = 27
6x - 4y = 12
Change the sign plus sign change into minus and minus sign change into plus
= - 5Y = 15
= y = 15/-5
=y = - 3
Putting y = - 3 in in equation 1.
6x - 9(-3) = 27
6x + 27 = 27
6x = 27 - 27
6x = 0
X = 0/6
X=0
