log₅(5x + 9) = log₅(6x)

Next step?

• 5x + 9 = 6x

• (5x + 9) + (6x)

• Divide both sides by 6.

• Subtract 9 on both sides.

log₂(1 - 4n) = log₂(2n + 43)

Next step?

• Subtract 2n on both sides.

• Subtract 1 on both sides.

• 1 - 4n = 2n + 43

• Square both sides.

log₉(6 - 3w) = log₉(-2w)

Next step?

• 6 - 3w = -2w

• Subtract 6 on both sides.

• Divide both sides by -2.

• Square both sides.

log₃(4x + 8) - 7 = -3
Next step?

• Add 7 to both sides.

• 3^-3 = 4x + 8

• 4x + 8 = 10

• 4x + 1 = -3

5ⁿ⁺¹⁰ = 25

Next step?

• 5ⁿ⁺¹⁰ = 5²

• 5(n + 10) = 25

• Subtract 10 on both sides.

• n + 10 = 25

13^c-8 - 9 = 17

Next step?

• Divide both sides by 13.

• Distributive Property

• log₁₃(c-8) = 17

• Add 9 to both sides.

9 ^. 12^r+4 - 8 = 127

Next step?

• Add 8 to both sides.

• Divide both sides by 9.

• Distributive Property

• r + 4 = 127

What is the first step you do to solve this equation?
