what is the x - value in the solution to this system of linear equations? 2x - y = 11 x + 3y = - 5 -3 -1 2 4

Explanation:

Step1: Isolate y in the first - equation

From $2x - y=11$, we get $y = 2x - 11$.

Step2: Substitute y into the second equation

Substitute $y = 2x - 11$ into $x + 3y=-5$. Then $x+3(2x - 11)=-5$. Expand the left - hand side: $x + 6x-33=-5$. Combine like terms: $7x-33=-5$.

Step3: Solve for x

Add 33 to both sides of the equation: $7x=-5 + 33$, so $7x=28$. Divide both sides by 7: $x=\frac{28}{7}=4$.
