Question 567960
5[2-3(6x-1)] 
you need to resolve -3(6x-1) first.
that becomes -3 * 6x - 3*-1 which becomes:
-18x + 3
your equation becomes:
5(2-18x+3)
combine like terms to get:
5(-18x+5)
simplify to get:
-90x + 25
that should be your answer.


to confirm that this answer is good, let x be any value that's easy to calculate and then solve the original equation and the final equation using that value of x.


if the answer from the original equation is the same as the answer from the final equation, then you did good.


in this case, i'll let x = 2.
the original equation is:
5(2-3(6x-1))
replace x with 2 and the equation becomes:
5(2-3(6*2-1)) which becomes:
5(2-3(12-1)) which becomes:
5(2-3(11) which becomes:
5(2-33) which becomes:
5(-31) which becomes:
-155


the final equation is:
-90x+25
replace x with 2 to get:
-90*2+25
simplify to get:
-180+25
simplify further to get:
-155


answers from the original equation and the final equation are the same so you can reasonably assume that the answer is correct.
final equation is -90x+24
