Answer 1

Answer:
The guy above has the answers already

Explanation:

Answer 2

3u + 40 + 2u = 6u - 30 - u = One solution
2.2x + 3z + 4.5 - 3.2 = One solution
4/5x + 2/3 + 1/5x = x = No solution
2.3y + 3.2 - y = 2.1 + 1.3y + 1.1 = Infinitely Many Solutions
2/3x + 2/3 + 1/5x = 2/3x = One solution
20 + 4r = 32 - 2r = One Solution
