A) U₁₀ = a + 9b U₂₀ = a + 19b a + 9b - a + 19b = 70 -10b = 70 b = -7 b ) U₁₅ = a + 14b U₇ = a + 6b a + 14b - a + 6b = -1 8b = - 1 b = - 1/ 8

iya sama - sama dek semoga lebih faham
a. a + 9b - ( a + 19b ) =70
-10b = 70
b = -7
b. a + 14b - ( a + 6b ) = -1
8b = -1
b = - 1/8
U₂₀ = a + 19b
a + 9b - a + 19b = 70
-10b = 70
b = -7
b ) U₁₅ = a + 14b
U₇ = a + 6b
a + 14b - a + 6b = -1
8b = - 1
b = - 1/ 8
