Question

Solve the pair of linear equations by cross-multiplication method.

2x - 3y = 7 and 3x + 2y = 4.​

Answer 1

Step-by-step explanation:

2x-3y=7 __1

3x-2y=4 __2

Now use a cross- multiplecation method

A1 = 2 , B1 = -3 , C1 = -7

A2 = 3 , B2 = -2 , C2 = -4

= X. Y. 1

--------- = -----------. =. ---------

B1. C1. C1 A1. A1. B1

--- × ---- --- × ---. --- × ---

B2 C2. C2. A2. A2. B2

Now put value And get answers.
