Answer:
Let 2x + y - 10 = 0 be equation (a).
Let x - y - 5 = 0 be equation (b).
Make y the subject in equation (b):
[tex]{ \tt{x - y - 5 = 0}} \\ { \tt{y = x - 5}}[/tex]
Substitute for y in equation (a):
[tex]{ \tt{2x + (x - 5) - 10 = 0}} \\ { \tt{3x - 15 = 0}} \\ { \tt{3x = 15}} \\ { \tt{x = 5}}[/tex]
Find y in any equation of your choice:
[tex]{ \tt{y = (5) - 5}} \\ y = 0[/tex]
