Q1. 4x + 3y = 9 and 8x + 27y = 81
where a1 = 4 and
a2 = 8
b1 = 3 and
b2 = 27
c1 = 9 and
c2 = 81
Now lets check whether -
b1/b2 = c1/c2 or b1/b2 = c1/c2
If any of the above condition matched only then we can use this method to solve the equation.
In the above question as we see its matched with the condition 2 so -
b1/b2 = c1/c2
3/27 = 9/81
1/9 = 1/9
If the condition satisfied then we take x equals to 0.
x = 0
3y = 9
y = 9/3
y = 3/1
y = 3/1
Q1. 2x + 3y = 7 and 4x + 8y = 14
where a1 = 2 and
a2 = 4
b1 = 3 and
b2 = 8
c1 = 7 and
c2 = 14
Now lets check whether -
b1/b2 = c1/c2 or b1/b2 = c1/c2
If any of the above condition matched only then we can use this method to solve the equation.
In the above question as we see its matched with the condition 1 so -
a1/a2 = c1/c2
2/4 = 7/14
1/2 = 1/2
If the condition satisfied then we take y equals to 0.
y = 0
2x = 7
y = 7/2
y = 7/2
y = 7/2
