12/x = 15/8
96 = 15x
x= 6.4 or 32/5
A is the answer sir if I’m wrong I’m sorry but I’m sure
Answer:
Linear systems are systems of equations in which the variables are never multiplied with each other but only with constants and then summed up
(9 - 7 X 3 + 4 )²
Always follow the rule

First look at the Brackets
There are no indices in the brackets
There is no division in the brackets
There is a Multiplication in the brackets 7 x 3
For the answer
(9 - 7 x 3 + 4)²
Brackets
Multiplication 7 x 3 = 21
(9 - 21 + 4)²
Addition -21 + 4 = -17
(9 - 17)²
Subtraction 9 - 17 = -8
-8²
Now start again once the brackets are gone
-8²
Indices
-8 x -8 = 64
-3A +3 = -24
Divide by -3
A -1 = 8
Add 1
A = 9
