x+4+x+8÷2=19

x+4+x+8÷2=19x+x=2x and 4+8=12

x+4+x+8÷2=19x+x=2x and 4+8=122x+12÷2=19

x+4+x+8÷2=19x+x=2x and 4+8=122x+12÷2=192x+12=19×2=38(by transposition we changed the sing and multiply it to 19)

x+4+x+8÷2=19x+x=2x and 4+8=122x+12÷2=192x+12=19×2=38(by transposition we changed the sing and multiply it to 19)2x+12=38

x+4+x+8÷2=19x+x=2x and 4+8=122x+12÷2=192x+12=19×2=38(by transposition we changed the sing and multiply it to 19)2x+12=382x=38-12

x+4+x+8÷2=19x+x=2x and 4+8=122x+12÷2=192x+12=19×2=38(by transposition we changed the sing and multiply it to 19)2x+12=382x=38-122x=26

x+4+x+8÷2=19x+x=2x and 4+8=122x+12÷2=192x+12=19×2=38(by transposition we changed the sing and multiply it to 19)2x+12=382x=38-122x=26x=26÷2
