-5(2w+1)=25

Question

can someone give me step by step insructions to solve this question because I don't understand what I am supposed to do first

Answer 1

-5(2w+1)=25

remove the parentheses.
-10w-5 = 25
add 5 to both sides.
-10w-5+5 = 25+5
combine terms
-10w = 30
multiply both sides by -1
10w = -30
divide both sides by 10
10w/10 = -30/10
w = -3

Check it by substituting -3 into the original equation.
-5(2w+1) = 25
-5(2*-3 + 1) = 25
-5(-6+1) = 25
-5(-5) = 25
25=25 which poves -3 is the correct answer for w.
Voila!
