Explanation:
"distribute parenthesis on the right side of the equation"
20=14+3x+24
rArr20=38+3x
"subtract 38 from both sides"
20-38=cancel(38)cancel(-38)+3x
rArr-18=3x
"divide both sides by 3"
(-18)/3=(cancel(3) x)/cancel(3)
rArrx=-6
color(blue)"As a check" Substitute this value into the right side of the equation and if equal to the left side then it is the solution.
14+3(2)=14+6=20="left side"
rArrx=-6" is the solution"
Explanation:
