\

The equations are $\"\"$ and $\"\"$ .

\

$\"\"$ Equation (1)

\

$\"\"$ Equation (2)

\

Since $\"\"$ , substitute $\"\"$ for x in the first equation.

\

$\"\"$

\

$\"\"$ (Apply distributive property: $\"\"$ )

\

$\"\"$ (Multiply: $\"\"$ )

\

$\"\"$ (Add: $\"\"$ ) $\"\"$

\

According to subtractionn property of equality: Subtract 2 from each side.

\

$\"\"$

\

$\"\"$ (Apply commutative property of addition: $\"\"$ )

\

$\"\"$ (Apply additive inverse property: $\"\"$ )

\

$\"\"$ (Apply additive identity property: $\"\"$ )

\

$\"\"$ (Subtract: $\"\"$ )

\

$\"\"$ (Multiply each side by negative one)

\

$\"\"$ (Product of two same signs is positive) \ \ $\"\"$

\

Now, find the x value by substituting $\"\"$ in Equation 2.

\

$\"\"$

\

$\"\"$ (Product of two same signs is positive)

\

$\"\"$ (Add: $\"\"$ ) $\"\"$

\

The solution is $\"\"$ .
