\"\"

\

The system of equations are \"\" and  \"\".

\

\"\"    Equation (1)

\

\"\"  Equation (2)

\

Solve the first  equation for c.

\

Apply addition property of equality: Add 5d to each side.

\

\"\"

\

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

\

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

\

Substitute \"\" in \"\".

\

\"\"

\

Distribute terms using distributive property: a( b + c ) = ab + ac.

\

\"\"

\

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

\

\"\"         (Add: \"\")\"\"\"\"  (Add 48 to each side)

\

Rearrange the terms using commutative property of addition: a + b = b + a. \ \

\

\"\"

\

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

\

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

\

\"\"                  (Add: \"\")\"\"

\

Apply division property of equality: Divide each side by 17.

\

\"\"

\

\"\"                    (Cancel common terms)\"\"

\

Now, find the c value by substituting  \"\" in \"\".

\

\"\"

\

\"\"    (Multiply: \"\")

\

\"\"              (Add: \"\")\"\"

\

The system of solution is \"\".
