Solve a system of equations using any method

Full solution

Q. Solve.

\newline

x + 6y = -10

\newline

y = -2

\newline

(_____, _____)

Substitute $y = -2$ : Substitute $y = -2$ into the equation $x + 6y = -10$ and then simplify. $\newline$ Substitute $-2$ for $y$ in $x + 6y = -10$ . $\newline$ $x + 6(-2) = -10$ $\newline$ $x - 12 = -10$
Isolate variable term: Isolate the variable term to solve for $x$ . $x - 12 = -10$ $x - 12 + 12 = -10 + 12$ $x = 2$
Find ordered pair solution: We found: $\newline$ $x = 2$ $\newline$ $y = -2$ $\newline$ What is the solution in the form of an ordered pair? $\newline$ Substitute $x = 2$ and $y = -2$ into $(x, y)$ . $\newline$ The solution is $(2, -2)$ .
