3x - 15 - 6 = 0
3x = 21
X = 21/3
X = 7
9 = 1 ( mod8)
9⁶ + 7 = 1⁶ + 7 ( mod 8)
= 1 + 7 = 8
8 / 8 leaves a remainder of 0

27: 72 = x :9
27/72 = x /9
x = 27 x 9 /72
x = 3.375

Given that x added to itself 13 times gives 112:
x + 13x = 112
14x = 112
x = 112 / 14
x = 8
Given: x² = y³.
Raising both sides to the power 3 gives: x⁶ = y⁹.
Therefore, x²ᶻ = x⁶, so 2z = 6 and z = 3.
