Q. Find the solution to the system of equations.You can use the interactive graph below to find the solution.{−2x+2y=−43x+3y=−18x=□y=□
Write Equations: Write down the system of equations.The system of equations is given by:−2x+2y=−43x+3y=−18
Simplify Equations: Simplify the equations if possible.Both equations can be simplified by dividing by the common factor of the coefficients.For the first equation, divide by 2:2−2x+22y=2−4Which simplifies to:−x+y=−2For the second equation, divide by 3:33x+33y=3−18Which simplifies to:x+y=−6
Solve Simplified System: Solve the simplified system of equations.We now have the system:−x+y=−2x+y=−6We can add the two equations together to eliminate x:(−x+y)+(x+y)=−2+(−6)This simplifies to:2y=−8
Solve for y: Solve for y.Divide both sides of the equation by 2 to solve for y:22y=2−8y=−4
Substitute and Solve for x: Substitute the value of y back into one of the simplified equations to solve for x. Using the equation x+y=−6, substitute y=−4: x+(−4)=−6x−4=−6 Add 4 to both sides to solve for x: x−4+4=−6+4x=−2
