Use the linear combination method to solve this system of equations. what is the value of x

x = -3 2/3

Step-by-step explanation:

Adding the two equations gives the value of y:

(3x +7y) + (-3x -2y) = (31) + (-1)

5y = 30

y = 6

Substituting this value into the second equation, we have ...

-3x -2(6) = -1

-3x = 11 . . . . . . . . . . add 12

x = -11/3 = -3 2/3 . . divide by the coefficient of x
