Explicación paso a paso:
a)
[tex]2x + 10 = 16 \\ 2x = 16 - 10 \\ 2x = 6 \\ x = 3[/tex]
b)
10x-8=8x
10x-8x=8
2x=8
x=4
c)
45x=180+40x
45x-40x=180
5x=180
x=36
d)
[tex]9x - 1 = 107 - 3x \\ 9x + 3x = 107 + 1 \\ 12x = 108 \\ x = \frac{108}{12} = 9[/tex]
g)
[tex]3x - 7 = 17 \\ 3x = 21 \\ x = \frac{21}{3} = 7[/tex]
e)
2x+3=x-9
2x-x=-9-3
x=-12
