solve using elimination. 7x + y = -6 -7x + 7y = 14 (\\square, \\square)

Question

solve using elimination.
7x + y = -6
-7x + 7y = 14
(\square, \square)

Explanation:

Step1: Add the two equations to eliminate \(x\)

The first equation is \(7x + y = -6\) and the second is \(-7x + 7y = 14\). When we add them together:

$$ LATEXBLOCK0 $$

Step2: Solve for \(y\)

Divide both sides of \(8y = 8\) by 8:

$$ y=\frac{8}{8}=1 $$

Step3: Substitute \(y = 1\) into the first equation to find \(x\)

Substitute \(y = 1\) into \(7x + y=-6\):

$$ LATEXBLOCK1 $$

Answer:

\((-1, 1)\)
