Why is the solution of equation 3 (5x-6) = 3-20x the solution of equation A-3 / 10x = 2A + 10x? How to solve it Why is the solution of equation 3 (5x-6) = 3-20x also the solution of equation A-3 / 10x = 2A + 10x?

3(5x-6)=3-20x
The solution is: x = 0.6
Substituting A-10 / 3x = 2A + 10x, we can get the following results
a=-8
