Question

56(3х+8)=4984. 12(2х-4)=336. 5(а+2)+9=54. 17(5х-3)=1734. 6(3х+6)=2322

Answer 1

 56(3х+8)=4984.

168x+448=4984

168x=4984-448

168x=4536

x=4536:168

x=27

12(2х-4)=336.

24x-48=336

24x=336+48

24x=384

x=384:24

x=16

5(а+2)+9=54.

5a+10+9=54

5a=54-9-10

5a=35

a=35:5

a=7

17(5х-3)=1734.

85x-51=1734

85x=1734+51

85x=1785

x=1785:85

x=21

 6(3х+6)=2322

18x+36=2322

18x=2322-36

18x=2286

x=2286:18

x=127
