Use linear combination method to solve this systemof equations. what is the value of x? 3x+7y=31 -3x-2y=-1 a)-6 b)-3 2/3 c)3 2/3 d)6

Using the linear combination method, we can add 3x+7y=31 and -3x-2y=-1 together, which makes 5y=30.

Just divide both sides by 5, and your answer will be y = 6.

To solve for x, just substitute 6 in y in either equation and solve for x:

In short, the correct answer is B. -3 2/3

x+y = 29, 5x + 2y = 100
