Answer:x=1
Step-by-step explanation:(4x+-7)=(2x+-9)
We move all terms to the left:
(4x+-7)-((2x+-9))=0
We add all the numbers together, and all the variables
(4x-7)-((2x-9))=0
We get rid of parentheses
4x-((2x-9))-7=0
We calculate terms in parentheses: -((2x-9)), so:
(2x-9)
We get rid of parentheses
2x-9
Back to the equation:
-(2x-9)
We get rid of parentheses
4x-2x+9-7=0
We add all the numbers together, and all the variables
2x+2=0
We move all terms containing x to the left, all other terms to the right
2x=-2
x=-2/2
x=-1
