Question

6x + 5y =4
10x + 9y = 0

Answer 1

make the first equation into only one variable so that you can substitute that one variable into the second equation and get your answer.

6X equals 4 - 5y

now substitute

x equals 2 by 3 - 5x 6y

10 * 2 by 3 - 5 /6y

now multiply and simplify the second equation

20 / 3 - 5 6 y y equals 0
