Answer:
{y,x} = {-8,1}
Explanation:
Solve by Substitution :
// Solve equation [2] for the variable y
[2] y = -8x
// Plug this in for variable y in equation [1]
[1] (-8x) - 6x = -14
[1] - 14x = -14
// Solve equation [1] for the variable x
[1] 14x = 14
[1] x = 1
// By now we know this much :
y = -8x
x = 1
// Use the x value to solve for y
y = -8(1) = -8
Solution :
{y,x} = {-8,1}
