Answer:
y = -12/(4d - 7d)
Step-by-step explanation:
Step 1: Write equation
4dy + 12 = 7dy
Step 2: Solve for <em>y</em>
<u>Subtract 7dy on both sides:</u> 4dy + 12 - 7dy = 0
<u>Subtract 12 on both sides:</u> 4dy - 7dy = -12
<u>Factor out y:</u> y(4d - 7d) = -12
<u>Divide both sides by 4d - 7d:</u> y = -12/(4d - 7d)
