Answer 2

Explanation:

1).
`(1)/(2)g-4=2g-(1)/(2)g+4`

`(1)/(2)g-4=(3)/(2)g+4`

Since left side of the given equation is not equal to the right side, there will be one solution to the given equation.

2). -2.1b + 5.3 = b - 3.1b + 5.3

-2.1b + 5.3 = -2.1b + 5.3

Since left side of the equation is exactly same as right side of the equation.

Equation will have infinitely many solutions.

3).
`(3)/(4)w+(5)/(4)=(10)/(4)-(3)/(4)w`

`(3)/(4)w+(5)/(4)=(5)/(2)-(3)/(4)w`

Since left side of the given equation is not equal to the right side, there will be one solution to the given equation.

4). 5.7c - 1.5 + 3.2c = 7.8c - 1.5 + 1.1c

8.9c - 1.5 = 8.9c - 1.5

Left side of the equation is same as right side of the equation.

Therefore, there will be infinitely many solutions of the equation.
