Answer 2

Answer:

The solution of the equations is (1,-2).

Step-by-step explanation:

Given : Equations $\frac{7}{2}x-\frac{1}{2}y=\frac{9}{2}$ and $3x-y=5$

To find : What is the solution of the system of equations?

Solution :

Simplify the first equation,

$7x-y=9$  ....(1)

$3x-y=5$ .....(2)

Subtracting (2) from (1),

$7x-y-3x+y=9-5$

$4x=4$

$x=1$

Substitute in (1),

$7(1)-y=9$

$y=-2$

Therefore, the solution of the equations is (1,-2).
