Math Problem Statement
solve the equation by elimination type the ordered pair with no spaces -2x-6y=-8 and -x+6y=-22
Solution
To solve the system of equations using the elimination method, we start with:
Step 1: Add the equations
We observe that the terms in both equations have opposite signs, so adding the two equations will eliminate the term:
This simplifies to:
Step 2: Solve for
To find , divide both sides by :
Step 3: Substitute into one of the original equations
Now, substitute into Equation 2 to find :
Add 10 to both sides:
Now, solve for by dividing by 6:
Step 4: Write the solution as an ordered pair
The solution is and . Thus, the ordered pair is:
