thequestion i think it is littlebit wrong

Answer 2

Step-by-step explanation:

Solve equation [2] for the variable y

[2] y = -x - 4

// Plug this in for variable y in equation [1]

[1] 5x - 3•(-x -4) = -4

[1] 8x = -16

// Solve equation [1] for the variable x

[1] 8x = - 16

[1] x = - 2

// By now we know this much :

x = -2

y = -x-4

// Use the x value to solve for y

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

Solution :

{x,y} = {-2,-2}
