Explanation:
Collect terms in x on the left side of the equation and numeric values on the right side.
add x to both sides.
3x+x+9=cancel(-x)cancel(+x)+1
rArr4x+9=1 subtract 9 from both sides.
4xcancel(+9)cancel(-9)=1-9
rArr4x=-8 To solve for x, divide both sides by 4
(cancel(4) x)/cancel(4)=(-8)/4
rArrx=-2" is the solution"
