Answer:

a = - 2

Explanation:

Given x = a, y = 3 lies on the equation. That is the values satisfies the equation when substituted.

Find a :

Equation : 5x + 2y = - 4

5 ( a ) + 2 ( 3) = - 4

5a + 6 = - 4

5a + 6 - 6 = - 4 - 6 [ subtracting both sides by 6 ]

5a + 0 = - 10

5a = - 10

a = - 2 [ dividing both sides by 5]

[ fact check : If (-2 , 3 ) lies on the equation : 5x + 2y = - 4

5(-2) + 2( 3 ) = - 4

- 10 + 6 = - 4

- 4 = - 4 ]
