See the solution process below:
Explanation:
First, expand the terms within parenthesis on the left side of the equation by multiplying each term within the parenthesis by the term outside the parenthesis:
Next, subtract
Now, divide each side of the equation by
Explanation:
Firstly, distribute the bracket.
rArrcancel(4)cancel(-4)-8x=x-3
"subtract x from both sides"
-8x-x=cancel(x)cancel(-x)-3
rArr-9x=-3
"divide both sides by - 9"
(cancel(-9) x)/cancel(-9)=(-3)/(-9)
rArrx=1/3
color(blue)"As a check" Substitute this value into the equation and if the left side equals the right side then it is the solution.
1/3-3=1/3-9/3=-8/3larrcolor(red)" right side"
rArrx=1/3" is the solution"
