No Solutions and Infinite Solutions

[mathperson1]

I have a problem: 3x + 4 – 3x = 4 and I don't understand it, or how to find the number of solutions. Can someone help, please?

Simplify the Left-hand-side of the equation. What do you get (show work)?

Please show us what you have tried and exactly where you are stuck.​

If the choice is no solution of infinity many solutions then you should try any number for x (say x=0 or x=1) and if the equation is satisfied then there are infinity many solutions otherwise ....

Now this only works for one equation and ONLY one variable.

First, you should say "infinitely many solutions" rather than "infinite solutions". That last is ambiguous as you could be working in a number system that includes infinite numbers.

Second, you should start by trying to solve it and see what happens.

Start by simplifying 3x+ 4- 3x= 4 using the arithmetic operations you have learned.
