Question

1. \\( y = x - 1 \\)\\( y = 2x + 2 \\)step 1: substitute \\( y = \underline{quadquad} \\)step 2: equation becomes: \\( \underline{quadquad} \\)step 3: solve for \\( x = \underline{quadquad} \\)step 4: find \\( y = \underline{quadquad} \\)solution: \\( (\underline{quadquad}, \underline{quadquad}) \\)

Explanation:

Step1: Choose substitution expression

$y = x - 1$

Step2: Substitute into second equation

$x - 1 = 2x + 2$

Step3: Isolate and solve for $x$

$x - 2x = 2 + 1 \implies -x = 3 \implies x = -3$

Step4: Substitute $x$ to find $y$

$y = -3 - 1 = -4$

Answer:

Solution: $(-3, -4)$
