The equation which is equivalent to 60% of 25 is x = 0.6 * 25
An equation is used to show the relationship between variables, numbers.
Let x represent the value of 60% of 25. Hence:
x = 60% of 25
x = 0.6 * 25
Hence the equation which is equivalent to 60% of 25 is x = 0.6 * 25
x/25 = 60/100
6/10 = x/25
This is the function

Then factor 2 out

Divide both side by two and use the quadratic formula to get the following

X=3 And x=-2 and don't forget to Chek them
