Q. Find the solution of the system of equations.x−5y5x+10y=−24=−15
Analyze System: Analyze the system of equations to determine the best method to solve it.The system of equations is:1) x−5y=−242) 5x+10y=−15We can use either substitution or elimination. Since the second equation can be simplified by dividing by 5, we will use elimination after simplifying the second equation.
Simplify Second Equation: Simplify the second equation by dividing all terms by 5. 5x+10y=−15Divide by 5:x+2y=−3Now we have the simplified system:1) x−5y=−242) x+2y=−3
Eliminate x: Subtract the second equation from the first to eliminate x.(x−5y)−(x+2y)=−24−(−3)This simplifies to:−7y=−21
Solve for y: Solve for y.Divide both sides by −7:y=−7−21y=3
Substitute and Solve for x: Substitute the value of y back into one of the original equations to solve for x. Using the first equation: x−5y=−24x−5(3)=−24x−15=−24
Substitute and Solve for x: Substitute the value of y back into one of the original equations to solve for x. Using the first equation: x−5y=−24x−5(3)=−24x−15=−24 Solve for x. Add 15 to both sides: x=−24+15x=−9
