I need to find a solution pls.

Sagot :

Answer:

x = - 2 , y = 4

Step-by-step explanation:

given the system of equations

2x + y = 0 ( subtract 2x from both sides )

y = - 2x → (1)

5x + 3y = 2 → (2)

substitute y = - 2x into (2)

5x + 3(- 2x) = 2

5x - 6x = 2

- x = 2 ( multiply both sides by - 1 )

x = - 2

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

substituting into (1)

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

The solution is x = - 2 , y = 4
