What is the x-value in the solution to this system of linear equations?

ASHA 777 [7]

Answer:

Step-by-step explanation:

The y-variable can be eliminated by adding 3 times the first equation to the second:

3(2x -y) +(x +3y) = 3(11) +(-5)

7x = 28 . . . . simplify

x = 4 . . . . . . . divide by 7

_____

Using Cramer's Rule, you can also find the x-value. The math is not so different.

x = ((-1)(-5) -(3)(11))/(-1(1) -3(2)) = -28/-7 = 4
