Solving brackets 19  3(2x  1)=7 Brackets cannot be solved. doing multiply or divide. 19  6x (3)=7 19  6x +3=7 adding or subtracting what ever needs to be done. 226x=7 adding 6x on both sides 226x+6x=7+6x 22=7+6x subtracting 7 on both sides 227=7+6x7 15=6x 6x=15 divide both sides by 6 \[\frac{ 6x }{ 6 } = \frac{ 15 }{ 6}\] \[x = \frac{ 15 }{ 6 }\] \[x= \frac{ 5 }{ 2 }\] Cant write in improper fraction. converting into decimals x=2.5
