Suppose a linear equation in one variable, x, is simplified. Which of the following resulting equations would indicate that the original equation has infinitely many solutions. -4=-4, 11=x, 0=0, x=0, 1=-1, x=x

So don't take my word i'm not exactly a mathematical person but i would assume a. because while selling the soap every month you increase in sells so you would by 11 percent. the you would get the factor 0.89 which if i had to guess would be the monthly profit over 11 probably wrong tho
