Question

-5(2w+1)=25 how do I solve this problem

Answer 1

-5(2w+1)=25

Multiply both sides by -5

(-5)(2w)=-10w

(-5)(1)=-5

-10w-5=25

Move -5 to the other side. Sign changes from -5 to +5.

-10w-5+5=25+5

-10w=30

Divide by -10 for both sides

-10w/-10=30/-10

w=-3

Answer: w=-3

Answer 2

Explanation:

Divide by - 5

-5(2w + 1) / - 5 = 25 / - 5

2w + 1 = - 5

Subtract 1 from both sides.

2w + 1 - 1 = - 5 - 1

2w = - 6

Divide by 2

2w/2 = -6/2

w = - 3
