Answer:
1.
[tex]9 + (2 \times x) = 13[/tex]
2.
[tex]2 - 2x = 0[/tex]
3.
[tex]6 \times (x + 4) = 42[/tex]
4.
[tex]5 - (9 \times x) = 31[/tex]
5.
[tex]12 \times (x + 10) = 34[/tex]
6.
[tex]10 + (4 \times x) = 54[/tex]
7.
[tex]6 \times (x + 2) = 20[/tex]
8.
[tex]x + (5 \times x) = 36[/tex]
9.
[tex]9 - 2x = 5[/tex]
10.
[tex](5 \times x )- 12 = 48[/tex]
11.
[tex]6 - 2x = 16[/tex]
12.
[tex]1 \times x = 16[/tex]
13.
[tex]9 \times x = 63[/tex]
14.
[tex]20 - (6 \times x) = 10[/tex]
15.
[tex]2x - 4 = 10 - x[/tex]
16.
[tex]2x + x = 90[/tex]
17.
[tex](x + 11) \times x = 84[/tex]
