Answer:

By arranging the equation

Explanation:

#6 - 3x + 6x = 18#

after multiplying 3 by the first term.

#6 + 3x = 18#

#3x = 18-6#

#3x = 12#

#x=12/3 = 4#

Answer:

#x=4#

Explanation:

#"distribute parenthesis on left side of equation"#

#6-3x+6x=18larrcolor(blue)"simplify left side"#

#rArr6+3x=18#

#"subtract 6 from both sides"#

#cancel(6)cancel(-6)+3x=18-6#

#rArr3x=12#

#"divide both sides by 3"#

#(cancel(3) x)/cancel(3)=12/3#

#rArrx=4#

#color(blue)"As a check"#

Substitute this value into the left side of the equation and if equal to the right side then it is the solution.

#(3xx-2)+(6xx4)=-6+24=18=" right side"#

#rArrx=4" is the solution"#
