#### 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"#
