Q. Find the solution of the system of equations.4x+y2x−8y=−43=4
Write Equations: Write down the system of equations to be solved.We have the following system of equations:4x+y=−432x−8y=4
Multiply to Eliminate y: Multiply the first equation by 8 to eliminate y.Multiplying the first equation by 8 gives us:8(4x+y)=8(−43)32x+8y=−344
Add Equations: Add the modified first equation to the second equation to eliminate y. We now have: 32x+8y=−3442x−8y=4 Adding these two equations together gives us: (32x+2x)+(8y−8y)=−344+434x=−340
Solve for x: Solve for x.Divide both sides of the equation by 34 to find x:3434x=34−340x=−10
Substitute x for y: Substitute x back into one of the original equations to solve for y. Using the first equation 4x+y=−43, we substitute x=−10: 4(−10)+y=−43−40+y=−43
Solve for y: Solve for y.Add 40 to both sides of the equation to isolate y:−40+y+40=−43+40y=−3
