Question

how many solutions are there to the equation 15x+11=8x

Answer 1

There is only one solution

Answer 2

\[15x+11=8x\]\[15x-8x=-11\]\[7x=-11\]\[x=-\frac{11}{7}\]

Answer 3

to have multiple solutions you would need a higher degree polynomial unless you had something like \[7x=0\]in which care there would be an infinite number of solutions
