Answer:
{y,x} = {-6,-2}
Step-by-step explanation:
/ Solve equation [2] for the variable y
[2] y = 2x - 2
// Plug this in for variable y in equation [1]
[1] (2x-2) - x = -4
[1] x = -2
// Solve equation [1] for the variable x
[1] x = - 2
// By now we know this much :
y = 2x-2
x = -2
// Use the x value to solve for y
y = 2(-2)-2 = -6

Answer:
![\sqrt[7]{b^{15}}](https://tex.z-dn.net/?f=%5Csqrt%5B7%5D%7Bb%5E%7B15%7D%7D)
Step-by-step explanation:
=> ![b^2*\sqrt[7]{b}](https://tex.z-dn.net/?f=b%5E2%2A%5Csqrt%5B7%5D%7Bb%7D)
