6x - 4y = 2 , X = 3 then x + y = ?

6*3 -4y = 2
18 - 4y = 2
18 - 2 = 4y
16 = 4y
y = 4

putting vallue of y in x + y = 4 + 3 = 7

=> 6x - 4y = 2
Taking 2 common from both sides.
=> 2(3X-2Y) = 2
=> 3x-2y = 1
Where X = 3
=> 3(3)-2y = 1
=> 9-1 = 2y
=> 2Y = 8
=> Y = 4

Therefore X+Y = 3+4 = 7

Answer is C

\(6x + 4y = 2\)
\(6*3 - 4y = 2\)
\(4y = 16\)
\(y = 4\)

\(x+y = 3 + 4 = 7\)

Given that X=3, using that in equation 6x-4y=2
y will be 4

x+y = 4+3=7 (C)
