Question

What is the solution of 2x-7y=6

Answer 1

Answer:

mark me as brilliant

Step-by-step explanation:

value of x

$2x - 7y = 6 \\ = > 2x = 6 + 7y \\ = > x = \frac{6 + 7y}{2}$

value of y

$2( \frac{6 + 7y}{2} ) - 7y = 6 \\ = > 12 + 14y - 7y = 6 \\ = > 12 + 7y = 6 \\ = > 7y = 6 - 12 \\ = > 7y = - 6 \\ = > y = \frac{ - 6}{7}$

final value of x

$2x - 7( \frac{ - 6}{7} ) = 6 \\ = > 2x + 42 = 6 \times 7 \\ = > 2x = 42 - 42 \\ = > 2x = 0 \\ = > x = 0$
