Answer:

5(4+2x)+5 =3(2x+5)4x+10

20+10x+5=6x+15+4x+10

25+10x=10x+25

10x-10x=25-25

0=0

This equation has zero solution.

check if the resulting expression is always true, sometimes true, or never true for all values of x.

We can simplify the given equation as follows:

5(4 + 2x) + 5 = 3(2x + 5) + 4x + 10

20 + 10x + 5 = 6x + 15 + 4x + 10 (distribute)

30 + 10x = 10x + 25 (combine like terms)

10x - 10x = 25 - 30 (move terms)

0 = -5

The simplified equation is always false, regardless of the value of x. Therefore, there are no solutions to this equation. In other words, there is no value of x that would make the original equation true.

So the answer is zero solutions.
