A-3b=4;2a=6b-9 Answer by elimination. Please include how you got to the solution. Apparently there is a solution to this problem

Step-by-step explanation:

a - 3b = 4 (eq1)

2a = 6b -9

or, 2a - 6b = -9 (eq2)

    2a - 6b = 8 (eq1) X 2

   2a - 6b = -9 (eq2)

(-)       (+)       (+)

the variable part of both the equations are same. so the equation has more than one solution.
