Answer:
Option 3,4,5 are correct.
Step-by-step explanation:
The system of equations are:
Multiply equation (2) with -3 and add with equation (1)
Value of y is 3
Putting value of y in eq(2)
Value of x is -2
So, Option 3,4,5 are correct.

x= 3+√5/4,3-√5/4
Step-by-step explanation:
1.In general, given ax^2+bx+c=0, there exists two solutions where:
x= -b+√b^2 - 4ac/2a, -b-√b^2-4ac/2a
2.In this case, a=4, b=-6 and c=1.
x=6+√(-6)^2-4×4/2×4, 6-√(-6)^2-4×4/2×4
3.Simplify.
x=6+2√5/8, 6-√5/8
4.Simplify solutions.
x=3+√5/4, 3-√5/4
