How do you solve the equation: x+(x+1)+(x+2)=9
Please show your work.
all the people I've asked to solve this equation, they were either too dumb or too busy to answer. How lame are they?

here you go:
x+(x+1)+(x+2)=9
x+x+1+x+2=9
3x+3=9
3x=9-3
3x=6
x=6/3
x=2

x+(x+1)+(x+2)=9
x + x + 1 + x + 2 = 9
3x + 3 = 9
3x = 9 - 3
3x = 6
x = 6/3 = 2

X=2
X+(X+1)+X+2)=9 equivalent 2+(2+1)+2+2)=9
or
2+3+4=9

Given:
x + (x + 1) + (x + 2) = 9
Step 1. Remove the parenthesis
x + x + 1 + x + 2 = 9
Step 2. Add all literal terms and numerical terms
3x + 3 = 9
Step 3. Transpose numerical term
3x = 9 - 3
Step 4. Perform algebraic addition
3x = 6
Step 5. Divide both terms of the equation by 3
x = 2 (Answer)
Hint.
This is a very fundamental algebraic operation (removing of parenthesis and combining like terms) that you should remember.
Good Luck!

that will be 3x+3=9
3x=9-3
3x=6
x=2; x+1=3; x+2=4
