Answer 2

2.1х ×(-5)= -10.5х
-4.5×(-3а)=13,5а

Answer 3

To solve this equation, let's break it down step by step:

1. 2.1x × (-5): Multiply 2.1x by -5. Result: -10.5x

2. -4.5 × (-3a): Multiply -4.5 by -3a. When multiplying two negative numbers, the result is positive. Result: 13.5a

So, the equation 2.1x × (-5) = -4.5 × (-3a) simplifies to -10.5x = 13.5a.
