Answer:

(2, 3 )

Step-by-step explanation:

5x - 4y = - 2 → (1)

2x + 4y = 16 → (2)

add (1) and (2) term by term to eliminate y

7x + 0 = 14

7x = 14 ( divide both sides by 7 )

x = 2

substitute x = 2 into either of the 2 equations and solve for y

substituting into (2)

2(2) + 4y = 16

4 + 4y = 16 ( subtract 4 from both sides )

4y = 12 ( divide both sides by 4 )

y = 3

solution is (2, 3 )

Answer:

( 2 , 3 )

Step-by-step explanation:

5x - 4y = - 2 ⇒ ( 1 )

2x + 4y = 16 ⇒ ( 2 )

( 1 ) + ( 2 )

5x - 4y + 2x + 4y = -2 + 16

7x = 14

Divide both sides by 7.

x = 2

Now let us take equation (1) to find the value of y.

5x - 4y = - 2

5 × 2 - 4y = -2

10 - 4y = -2

-4y = - 2 - 10

-4y = - 12

Divide both sides by ( -4 )

y = 3

Therefore,

( x , y ) ⇒ ( 2 , 3 )
