X-5y=-6x+2y=8a. 2/3b. 2c. 4d. 4 2/3

Answer
Option B is correct
y = 2
x = 4
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
