Question

13 + 2y = 9х
Зу = 7х
Solve these equation in simultaneous

Answer 1

Answer:

$x = 3 \\ and \\ y = 7$

Explanation:

$9x - 2y = 13...........(i) \times 3 \\ 7x - 3y = 0............(ii) \times 2 \\ \\ 27x - 6y = 39 \\ 14x - 6y = 0 \\ \\ 13x = 39 \\ x = 3$

Substitute x in eqn 1

$7(3) - 3y = 0 \\ - 3y = - 21 \\ y = 7$
