To solve 6x - 0.8 > 3x + 2.2, we need to isolate x by subtracting 3x from both sides:

6x - 3x - 0.8 > 2.2

3x - 0.8 > 2.2

Then, add 0.8 to both sides:

3x > 3

Finally, divide by 3 to find the value of x:

x > 1

Therefore, the solution for the inequality 6x - 0.8 > 3x + 2.2 is x > 1.

Moving on to the equation 7x - 3 = 5x + 1:

First, simplify the equation by combining like terms:

7x - 5x = 1 + 3

2x = 4

Next, divide by 2 to solve for x:

x = 2

Therefore, the solution for the equation 7x - 3 = 5x + 1 is x = 2.
