Question

2x - 3y = 1 ; 3x - 4y = 1 substitution method ​

Answer 1

Answer:

a^1/a^2=2/3

b^1/b^2=-3/-4 hence minus. minus will be cancelled.3/4

a^1/a^2 is not equal to b^1/b^2.

HENCE we can cross multiply the values and we will get the answer.

Answer 2

Answer:

Step-by-step explanation:

2x - 3y = 1

so x = (1 + 3y / 2)

put value in 3x - 4y = 1

3 ( 1 + 3y / 2 ) -4y = 1

3 + 9y / 2 - 4y = 1

3 + 9y -8y / 2 = 1

3 + y = 2

y = -1

put value

2x - 3 ( -1 ) = 1

2x + 3 = 1

2x = -2

x = -1
