Hola! :3
Resolvemos:
1) 4(x+4)=2(x+2)
4x+16=2x+4
4x-2x=4-16
2x= -12
x= -12/2
x= -6
2) 6(x+5)=5(x+5)
6x+30=5x+25
6x-5x=25-30
x= -5
3) 5(x-3)=4(x+4)
5x-15=4x+16
5x-4x=16+15
x=31
4) 3(3-x)+9=2(x-4)-6
9-3x+9=2x-8-6
18-3x=2x-14
18+14=2x+3x
32=5x
32/5=x
6.4=x
Saludos desde Perú :3
Espero haberte ayudado :D
