Question

The solution of the system of equations x+y=7 and x-y=1 is​

Answer 1

Answer:

x=4

y=3

x+y=7

4+3=7

x-y=1

4-3=1

Answer 2

Step-by-step explanation:

Here,

$a_1 = 1,b_1 = 1,c_1 = 7$

$a_2 = 1,b_2 = - 1,c_2 = 1$

From above we can see that

$\frac{a_1}{a_2} \neq \frac{b_1}{b_2}$

Hence the system of equation is intersecting and have unique solution.
