-8 I believe is the answer
Line a can be rewritten as
.. 2y -x = 12
The coefficients of y and x match those of line b, so lines "a" and "b" are parallel.
I think the answer would be 6.
Since n=8,
the equation could be rewritten as 4+(8-2)÷6
There is a rule called PEMDAS
Parenthesis
Exponents
Multiplication
Division
Addition
Subtraction
When solving equations, we should follow this rule.
Since there are parenthesis in the equation, we have to solve inside it first. Inside the parenthesis, we see the equation 8-2. 8-2 would equal 6. Then the whole equation would become 4+6÷3. Since division is the next operation in the equation(according to PEMDAS), we divide. 6÷3 would equal 2. Then the equation becomes 4+2. 4+2 would equal 6. Then the answer would be 6. I hope this helped :)
