The general form for a pair of linear equations in two variables x and y is
and
----- (1)
----- (2)
Comparing equations 1 and 2 with the general form of equation to write their co-efficient,
Compare the ratio,
If , then the pair of linear equations has exactly one solution.
So, it said to be consistent.
Let b>a
We are told that b=a+6 and that a+b=30
Using the value of b=a+6 in a+b=30 gives you:
a+(a+6)=30 combining like terms on left side
2a+6=30 subtract 6 from both sides
2a=24 divide both sides by 2
a=12, and since b=a+6
b=18
So the two numbers are 12 and 18.
Answer: subtraction property equality.
