Jawaban:

1.

[tex]5a + 2 = 4a - 6 \\ 5a - 4a = - 6 - 2 \\ a = - 8[/tex]

2.

[tex]7b - 8 = 5b + 10 \\ 7b - 5b = 10 + 8 \\ 2b = 18 \\ b = \frac{18}{2} \\ b = 9[/tex]

3.

[tex]2c - 3 = 7 - 3c \\ 2c + 3c = 7 + 3 \\ 5c = 10 \\ c = \frac{10}{5} \\ c = 2[/tex]

4.

[tex]3d + 6 = d - 10 \\ 3d - d = - 10 - 6 \\ 2d = - 16 \\ d = \frac{ - 16}{2} \\ d = - 8[/tex]

5.

[tex]5e - 13 = 10e + 2 \\ 5e - 10e = 2 + 13 \\ - 5e = 15 \\ e = \frac{15}{ - 5} \\ e = - 3[/tex]
