Answer 1

Bagian A

[tex]\sf \bf \sf 3x + 4 = 2(x - 1)[/tex]

[tex]\sf \bf \sf 3x + 4 = 2x -2[/tex]

[tex]\sf \bf \sf 3x - 2x = -2-4[/tex]

[tex]\sf \bf \sf 3x - 2x = -6[/tex]

[tex]\bold{\underline{\boxed{\pink{\sf \bf \tt x = -6}}}}[/tex]

Bagian B

[tex]\sf \bf \sf x² + 9x = 0[/tex]

[tex]\sf \bf \sf x(x+9)= 0[/tex]

[tex]\sf \bf \sf x = 0[/tex]

Maka :

[tex]\sf \bf \sf x + 9 = 0[/tex]

[tex]\sf \bf \sf x = 0 - 9[/tex]

[tex]\bold{\underline{\boxed{\pink{\sf \bf \tt x = -9}}}}[/tex]

Answer 2

Penjelasan dengan langkah-langkah:

a. 3x + 4 = 2(x - 1)

3x + 4 = 2x - 2

3x - 2x = -2 - 4

x = -6

b. x² + 9x = 0

(x + 9)(x + 1) = 0

x + 9 = 0

x = 9

x + 1 = 0

x = -1

Jadi, nilai x yang memenuhi adalah 9 atau -1.

Semoga membantu!!!
