I assume you want to find x
remember, you can do anything to an equation as long as you do it to both sides
7x-4=-2x+1+9x-5
group like terms
7x-4=-2x+9x+1-5
add like terms
7x-4=7x-4
add 4 to both sides
7x=7x
divide both sides by 7
x=x
true
x=all real numbers
since it sipmlifies to x=x (it could somiplify to 0=0 as well), it is an identity and all real numbers work for x
