Let's solve ~
[tex]\qquad \sf \dashrightarrow \:5 - ( 6 - 9x) = 1 - (4 - 10)[/tex]
[tex]\qquad \sf \dashrightarrow \:5 - 6 + 9x = 1 - 4 + 10[/tex]
[tex]\qquad \sf \dashrightarrow \: 9x - 1 = 7[/tex]
[tex]\qquad \sf \dashrightarrow \:9x = 8[/tex]
[tex]\qquad \sf \dashrightarrow \:x = \dfrac{8}{9} [/tex]
