Question

6x + 5y = 5
9x - 4y = 19

Solve this concurrent equation.​

Answer 1

6x=55y

9x=188y

sure it is concurent equation

Answer 2

`x = (5)/(3) , \ \ y = -1`

Explanation:

6x + 5y = 5 -----(1)

9x - 4y = 19 -----(2)

Multiply (1) by 9 : 54x + 45y = 45 ------(3)

Multiply (2) by 6 : 54x - 24y = 114 -------(4)

(3) - (4) ==> 69y = -69

y = -1

Substitute y = -1 in (1)

6x + 5(-1) = 5

6x - 5 = 5

6x = 5 + 5

6x = 10

`x =(10)/(6) = (5)/(3)`
