salam alaykum warahmatullah wabarakatuh
Could you please help me with these: I think it's called "Substitution Approach" in English.
a)
2x + y = 6
3x − y = 9
b)
2x + 3y = 16
3x + y = 10
c)
3x − 2y = 20
5x − 5y = 25
I hope anyone can show me the answers of x and y in simple ways. JazakAllah khayr.
Here are the answers actually, but I want help with how to work out the answers, what do I do to get the right answers:
a) x = 3 and y = 0
b) x = 2 and y = 4
c) x = 10 and y = 5
