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
