Simplify first like so, by adding like terms and distributing the 2 through the 2x+1

4x+3=4x+2+1

simplify again

4x+3=4x+3

subtract 3 from both sides

4x=4x

divide 4 from both sides

x=x

therefore, no matter what x is, both sides will always equal each other

Thus x has an infinite set of solutions
