Answer

Option B is correct

y = 2

x = 4

Step-by-step explanation

We need to solve the simultaneous equation

x - 5y = -6

x + 2y = 8

To do this, we will just subtract equation 2 from equaton 1 to eliminate x first

x - 5y = -6

x + 2y = 8

x - x - 5y - 2y = -6 - 8

0 - 7y = -14

-7y = -14

Divide both sides by -7

(-7y/-7) = (-14/-7)

y = 2

We can then solve for x

x - 5y = -6

x - 5(2) = -6

x - 10 = -6

x = -6 + 10

x = 4

Hope this Helps!!!
