Question

6x + 5y = 59x - 4y = 19Solve this concurrent equation.​

Answer 1

Answer:

$x = \frac{5}{3} , \ \ y = -1$

Step-by-step 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

               $x =\frac{10}{6} = \frac{5}{3}$

Answer 2

6x=55y

9x=188y

sure it is concurent equation
