What is the answer

80x+56=100

0.55

Step-by-step explanation:

We have to make the term that has x the subject of the equation. To do that, we subtract the term that doesn't have x from both sides.

Solving this gives us

Now we have to divide both sides by the coefficient of x, which in this case is 80. So we divide both sides by 80 as follows

Solving this gives 0.55
