Solve a system of equations using any method

Full solution

Q. Solve.

\newline

-3x - 3y = 9

\newline

x = 2

\newline

(_____, _____)

Substitute $x = 2$ : Substitute $x = 2$ into the equation $–3x − 3y = 9$ . $\newline$ Calculation: $–3(2) − 3y = 9$ $\newline$ $–6 − 3y = 9$
Isolate variable y: Isolate the variable $y$ . $\newline$ Calculation: $–3y = 9 + 6$ $\newline$ $–3y = 15$
Solve for y: Solve for y. $\newline$ Calculation: $y = \frac{15}{(\text{–}3)}$ $\newline$ y = $\text{–}5$
Find ordered pair: We found: $\newline$ $x = 2$ $\newline$ $y = -5$ $\newline$ What is the solution in the form of an ordered pair? $\newline$ Substitute $x = 2$ and $y = -5$ into $(x, y)$ . $\newline$ The solution is $(2, -5)$ .
