1. how many solitions does this equation have -4(5-3x)=12x+20
2. how many solutions does this equation have 3x+7(x+1)=2(6x+5)-2

The answers are:

1.  No solution.

2. One solution:

Step-by-step explanation:

In order to determine the solutions for both equations, we have to solve every one. In any equation of one variable, we could get three types of solution:
