The given linear system is
Rewrite the equations in slope intercept form
.

(Subtract 3x from each side)
(Apply commutative property:
)
(Apply additive inverse property:
) \ \
(Apply additive identity property:
)
(Divide each side by 2)
(Cancel common terms) \ \
(Distribute the common denominator)
(Divide:
)

(Divide each side by 4)
(Cancel common terms)
(Distribute the common denominator)
(Divide:
)
(Divide:
)
Since two slope intercept forms are equal.So, the graphs of the equations are the same line.
\The lines have infinitely many points of intersection.
\
The linear system has infinitely many solutions. Any point on the line
is a solution.
