Explicación paso a paso:
a) 5x - 11 = 2x + 10
5x-2x=10+11
3x=21
x=7
b) 7x - 22 = 10x + 23
-23-22=10x-7x
-45=3x
-15=x
c) 5x + 3 = 2x + 9
5x-2x=9-3
3x=6
x=2
d) 4x + 2 (x + 3) = 2 (x + 12)
4x+2x+6=2x+24
6x+6=2x+24
6x-2x=24-6
4x=18
x=4.5 o 9/2
e) 3x + 2 (2x - 1 ) = 3 (× + 2) -4
3x+4x-2=3x+6-4
7x-2=3x+2
7x-3x=2+2
4x=4
x=1
f) 5x - 5 (2x + 1) = -3 (4x + 5)
5x-10x-5=-12x-15
-5x-5=-12x-15
15-5=-12x+5x
10=-7x
10/-7 =x
