Question 1168902: Which is the best step to take to solve the following system of linear equations?
2x - 3y = 13
x - y = 5
a. Add the equation x - y = 5 and x - 3y = 6.5
b. Subtract the equation x - y = 5 from the equation x - 3y = 6.5
c. Subtract the equation 2x - 2y = 10 from the equation 2x - 3y = 13
d. Add the equations 2x - 3y = 13 and 3x - 3y = 15
