Q. Solve using elimination.(_____, _____)
- Set Up Equations: First, we need to set up the equations to eliminate one of the variables. We have the following system of equations:We can see that the coefficients of are opposites, which means we can add the two equations together to eliminate the variable.
- Add Equations: Now, let's add the two equations together:This simplifies to:
- Combine Like Terms: Next, we combine like terms:
- Solve for x: Now, we solve for x by dividing both sides by :
- Substitute x Value: With the value of found, we can substitute into one of the original equations to find the value of . We'll use the first equation:
- Perform Multiplication: Now, we perform the multiplication:
- Isolate y Term: Next, we add to both sides to isolate the term with :
- Solve for y: Finally, we divide both sides by to solve for :
