Question

0.22 (x+6) = 0.2x + 1.8

Answer 1

0,22x + 1,32 = 0,2x + 1,8
0,22x - 0,2x = 1,8 - 1,32
0,02x = 0,48 |:0,02
x = 24

:)

Answer 2

Your answer would be x=24.
0.22x+1.32=0.2x+1.8
0.22x+1.32 - 0.2x = 0.2x + 1.8 - 0.2x
0.02x+ 1.32 = 1.8
0.02x + 1.32 - 1.32 = 1.8-1.32
0.02x = 0.48
0.02x/0.02 = 0.48/0.02
x=24!
