    It has no solution. It has one solution. It has two solutions. It has infinitely many solutions.

    try to solve it first if you get equal sides then infinitely many solution example 4=4 if both sides are not equal then no solution like 9=7

    3x − 3x − 2 = −2 no solution add 2 on both sides 3x-3x=-2+2 0=0

    This solution could also be stated as "all real numbers" or "all reals" or "the whole number line"; expect some variation in lingo from one text to the next. Note that, if I had solved the equation by subtracting a 5 from either side of 5 + 4x = 5 + 4x to get "4x = 4x", I would have ended up with nothing other than another trivially-true statement. I could also have subtracted both 4x and 5 from both sides to get "0 = 0", but the solution would still be the same: "all x". Don't be surprised if, for "all real numbers" or "no solution" equations, you don't necessarily have the exact same steps as some of your fellow students. Since there are infinitely-many always-true equations (like "0 = 0") and infinitely-many nonsensical equations (like "3 = 4"), there will be many ways of arriving at these answers

    you can substitute x by any number you will get equal sides \[\huge\rm 3(9)-3(9)-2=-2\] or let plug in 2 \[\huge\rm 3(-2)-3(-2)-2=-2\] both sides are e qual how can you say that there is no solution ?
