Question

x+y=7 , 3x-y=1 pair of equation by substitution method (full method with both x and y values)

Answer 1

Answer:

x=2   and   y=5

Explanation:

x+y=7                   3x-y=1   (1)

y=7-x  (2)

put value of y in (1)

3x-(7-x)=1

3x-7+x=1

4x-7=1

4x=8

or x=2

put value of x in (2) to get value of y

y=7-2

or y=5
