Answer:
{x,y}={-8,-5}
Step-by-step explanation:
/ Solve equation [2] for the variable y
[2] y = 6x + 43
// Plug this in for variable y in equation [1]
[1] -x + 2•(6x+43) = -2
[1] 11x = -88
// Solve equation [1] for the variable x
[1] 11x = - 88
[1] x = - 8
// By now we know this much :
x = -8
y = 6x+43
// Use the x value to solve for y
y = 6(-8)+43 = -5
Solution :
{x,y} = {-8,-5}
hope this helps!
