Q. What is the result of adding these two equations?−5x−9y5x−9y=3=−2
Identify operation to combine: Identify the operation to combine the equations. Since the coefficients of 'x' in both equations are opposite, we can add the equations to eliminate 'x'.
Add equations to eliminate 'x': Add the equations to eliminate 'x'. (−5x−9y)+(5x−9y)=3+(−2)−5x+5x−9y−9y=3−2The x terms cancel each other out, and we are left with −18y=1.
Simplify the equation: There is a mistake in the previous step. The correct calculation should be −5x+5x−9y−9y=3−2, which simplifies to −18y=1. However, the correct simplification is −18y=1.
