-(10x-3x-4)=-3-(12x-12-3x)
We move all terms to the left:
-(10x-3x-4)-(-3-(12x-12-3x))=0
We add all the numbers together, and all the variables
-(7x-4)-(-3-(9x-12))=0
We get rid of parentheses
-7x-(-3-(9x-12))+4=0
We calculate terms in parentheses: -(-3-(9x-12)), so:We get rid of parentheses
-3-(9x-12)
determiningTheFunctionDomain -(9x-12)-3
We get rid of parentheses
-9x+12-3
We add all the numbers together, and all the variables
-9x+9
Back to the equation:
-(-9x+9)
-7x+9x-9+4=0
We add all the numbers together, and all the variables
2x-5=0
We move all terms containing x to the left, all other terms to the right
2x=5
x=5/2
