Question

Tentukan nilai A & B yang memenuhi
x + 2 = (2 + 2b)x + 3b - 5a

Answer 1

X + 2 = (2 + 2b)x + 3b - 5a
2 + 2b = 1
2b = 1 - 2
2b = -1
b = -1/2
3b - 5a = 2
3(-1/2) - 5a = 2
-3/2 - 5a = 2
-5a = 4/2 + 3/2
-5a = 7/2
a = 7/2 × -1/5
a = -7/10

Answer 2

Jawab :
= x + 2 = (2 + 2b) x + 3b - 5a
= 2 + 2b
= 1
2b = 1 - 2
2b = -1
b = -1/2
= 3b - 5a
= 2
= 3(-1/2) - 5a
= 2
= -3/2 - 5a
= 2
= -5a
= 4/2 + 3/2
= - 5a
= 7/2
a = 7/2 × -1/5
a = -7/10
