w represents the amount of water added.
890 + w = 4(170 + w)
890 + w = 680 + 4w
Can you solve for w?

Do you know how to solve an equation with one variable?

The problem said that after water was added
the big tank contained 3 times as much water
as the small tank. You mistyped and put 4.
890 + w = 3(170 + w)
890 + w = 510 + 3w
To continue:
1. Subtract w from both sides
2. Subtract 510 from both sides
3. Divide both sides by the coefficient of w ... that should be 2 at that point
