Answer:
[tex] - 7[/tex]
Step-by-step explanation:
-6 x + 3 = 45
collect like terms and then make x the subject of formula
=> -6x = 45 -3
note: when turning three over to the other side the plus sign change to minus
In order to make x the subject of formula we divide 45 - 3 by -6
=> [tex] \frac{45 - 3}{ - 6}\\ [/tex]
subtract 45 from 3 which gives us 42
now divide 42 by -6
=> -7
