Question

Solve x and y by cross multiplication method where 2x + 3y is equal to 7 and 6x-5y=11

Answer 1

Step-by-step explanation:

here is your answer.....

Answer 2

SOLUTION

The given Equation be as

2x +3y= 7.....(1)

6x -5y= 11......(2)

Now, by cross multiplicationz we get

$= > \frac{x}{(11 \times3) - (7 \times - 5)} = \frac{y}{(7 \times6) - (11 \times 2) } = \frac{1}{(2 \times 5) -(6 \times 3) } \\ \\ = > \frac{x}{33 + 35} = \frac{y}{42 - 22} = \frac{1}{10 - 18} \\ \\ = > \frac{x}{68} = \frac{y}{20} = \frac{1}{ - 8} \\ \\ = > \frac{x}{68} = \frac{1}{ - 8} \: \: and \: \: \frac{y}{20} = \frac{1}{ - 8} \\ \\ = > x = - \frac{68}{8} \: \: and \: \: y = - \frac{20}{8}$
