Step-by-step explanation:
1).
Comparing exponents on both the sides.
x² + 2x = -1
x² + 2x + 1 = 0
(x + 1)² = 0
x = -1
2).
By comparing exponents,
x - 3 = 3(x + 1)
x - 3 = 3x + 3
3x - x = 3 + 3
2x = 6
x = 3
3).
By comparing exponents,
5 - k = 2(3 - k)
5 - k = 6 - 2k
2k - k = 6 - 5
k = 1
4).
By comparing exponents,
x + 3 = 3(2x + 6)
x + 3 = 6x + 18
6x - x = 3 - 18
5x = - 15
x = -3
5).
x - 2 = 0
x = 2
