X² - 8x = -10
to have a complete square, we must have this format:
a² + 2ab + b²
a² = x²
2ab = -8x ⇒ 2(x)(-4)
b² = -4² = 16
x² - 8x + 16 = -10 + 16
x² - 8x + 16 = +6
(x-4)² - 6 = 0
Both sides must have an additional value of 16.

Answer:
x = 29
Step-by-step explanation:
-58 - 7x = -10x + 29
-58 + 3x = 29
3x = 87
x = 29
