Answer

No solution. The solution set is empty.

Work Step by Step

$3x+\frac{y}{2}=2$ Equation $(1)$ $6x+y=5 $ Equation $(2)$ From Equation $(1)$ $3x+\frac{y}{2}=2$ Taking LCD, $\frac{6x+y}{2}=2$ $6x+y=4$ Equation $(3)$ Subtract Equation $(3)$ from Equation $(2)$ $6x+y -(6x+y)=5 -4$ $6x+y -6x-y=1$ $0=1$ The resulting equation is false for all values of $x$ or $y$. Thus the system has no solution. The solution set is empty.
