Answer:
use BODMAS
brackets
of
division
multiplication
addition
subtraction
or Americans would use BEDMAS I think
so it'll be 8 + 4 ÷ (-24) × (3) - 4 = 35
u can break the brackets down further
Since the second equation gives a value for a, we can substitute it into the other equation to find a value for B.
Let's substitute b-2 into the first equation wherever there is an a.
a - 3b = 4
(b-2) - 3b = 4
b - 2 - 3b = 4
-2 - 2b = 4
-2b = 6
b = -3
Now let's find a by substituting -3 into either of the equations to find the value of a.
a = b - 2
a = -3 - 2
a = -5
So your solution set is (-5, -3)
