How do you do 1/4 (16x+20) - 7x

Distribute the 1/4:

1/4 (16x) + 1/4 (20) - 7x

Do the multiplication:

1/4 (16x) = 16x/4 = 4x

1/4 (20) = 20/4 = 5

Now you have:

4x + 5 - 7x = 0

Combine like terms (4x and - 7x):

-3x + 5 = 0

Subtract 5 from both sides:

-3x = - 5

Divide by - 3:

x = - 5/-3 = 5/3

Answer:

x = 5/3
