-6 (0,5х -1,5) - 4,5 - 8х = 2/3
-3 х + 9 - 4,5- 8х = 2/3
-3х - 8х = -  9 +4,5 +2/3
-11 х = - 4,5 +2/3
- 11 х = -45/10 +2/3 = -135/30 +20/30
-11х = - 115/30
       х =

Read this blog by Helen Randall about the ideal school

Many people who go to school think life will be better after they leave. Adults tell you that school days are the best days of your life and you wonder what the rest of your life will be like if this is the best! First of all, the school day is really long. Lots of adults work long hours too, but school

isn't better at all. Why can't we start a bit later and leave a bit earlier? Also, students have to do

homework, so we don't get as much free time as adults. We should have more time to do things

like sleeping. As everyone knows, teenagers need a lot of sleep! As for subjects, we have to do all of them, even the ones we don't enjoy. Adults can

choose the job they do. Ofcourse it is impossible to get a job if you can't read or write but why do we have to learn about History and Chemistry? I'd like to do more creative subjects like Photography and Art, and also more class activities outside the classroom. So, what about life after school? Adults say we don't know what it's like, but what do they teach us about it?! We don't know how to manage money or how to apply for a job ... so come on teachers, it's not just about doing homework and passing exams!​
