Question

4dy + 12 = 7dy, solve for y. Show how you solved it

Answer 1

Answer:

y = -12/(4d - 7d)

Step-by-step explanation:

Step 1: Write equation

4dy + 12 = 7dy

Step 2: Solve for y

Subtract 7dy on both sides: 4dy + 12 - 7dy = 0

Subtract 12 on both sides: 4dy - 7dy = -12

Factor out y: y(4d - 7d) = -12

Divide both sides by 4d - 7d: y = -12/(4d - 7d)

Answer 2

Hello! :)

First thing you do is add -7dy to both sides

4dy + 12 + -7dy = 7dy + -7dy

-3dy + 12 = 0

Next you will have to add -12 to both sides

-3dy + 12 + -12 = 0 + -12

-3dy = -12

Last thing you have to do is divide both sides by -3d

-3dy/-3d = -12/-3d

y = 4/d (ANSWER)
