Answer 1

Jawaban:

1.)

[tex]2x + 1 = 9 \\ 2x = 9 - 1 \\ 2x = 8 \\ x = \frac{8}{2} \\ x = 4[/tex]

2.)

[tex]4x - 5 = - 13 \\ 4x = - 13 + 5 \\ 4x = - 8 \\ x = \frac{ - 8}{4} \\ x = - 2[/tex]

3.)

[tex]3x = - 2x - 15 \\ 3x + 2x = - 15 \\ 5x = - 15 \\ x = \frac{ - 15}{5} \\ x = - 3[/tex]

4.)

[tex]2x = 3x - 8 \\ 2x - 3x = - 8 \\ - x = - 8 \\ x = 8[/tex]
