almond37 [142]

Answer: A=1

Explanation:

First, distribute the 3: 3x3A, 3x-5, the equation is now 2A+9A-15= -4

Now add the 2A plus 9A, the equation is now 11A-15= -4

Solve algebraically:

11A-15= -4

+15   +15                                                                                                 11A=11                                                                                                     Divide by 11 on each side
