Option( c ) is the correct one.
-2x +y= -3
x= (3+y)/2
By executing the value in second equation
{-(3+y)/2} +2y =3
( -3-y +4y)/2 =3
-3 +3y =6
3y = 9
y = 3
Again by substituting the value of y in any of the equation
-2x +y =-3
-2x =-6
x= 3.
Answer:
Perimeter = 17a
Area = 30 square meters
Step-by-step explanation:
Perimeter = 2b + 8 = 10b + 5 + a = 15ab + 2a - b = 17a
Area = 2 + 8 = 10 + 2 = 12 × 5 = 60 simplify
I honestly don't know if this is correct, I hope it is
