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"#
