You could use
3x +22x for basics, or for more harder ones, you could use 16x= 4x+ _x
OR Harder is Simplify- 32x+5x+72y+32x+26y=___
If not that, then maybe Simplify- (3y+5x)2nd power * 32x+17y-3
These are some examples. Enjoy!

You use variable in math problems to help you solve the answer. For example, you could do 50+50=a. The (a) would be the variable. Or for that same problem you could do 50+y=100. Then the (y) would be the variable.
In math, x can either be a multiplication symbol, (ex/ 3 x 4=12), or it is used as a general variable in algebra problems (2x=4)
There are several websites that you can use to get help with math problems. Some of those sites are wwww.webmath.com and www.mathway.com.
any number at all
A variable is an unknown number represented by a letter
