Q. Find the solution of the system of equations.3x+12y−5x+6y=−33=3
Write Equations: Write down the system of equations to be solved.We have the following system of equations:3x+12y=−33−5x+6y=3
Multiply Second Equation: Multiply the second equation by 2 to make the coefficients of y the same.Multiplying the second equation by 2 gives us:−10x+12y=6Now our system of equations is:3x+12y=−33−10x+12y=6
Eliminate y: Subtract the second equation from the first equation to eliminate y.(3x+12y)−(−10x+12y)=−33−6This simplifies to:3x+12y+10x−12y=−33−6Which further simplifies to:13x=−39
Solve for x: Solve for x.Divide both sides of the equation by 13 to isolate x:1313x=13−39x=−3
Substitute and Solve for y: Substitute x=−3 into one of the original equations to solve for y.Using the first equation 3x+12y=−33, substitute x with −3:3(−3)+12y=−33−9+12y=−33
Substitute and Solve for y: Substitute x=−3 into one of the original equations to solve for y. Using the first equation 3x+12y=−33, substitute x with −3: 3(−3)+12y=−33−9+12y=−33 Solve for y. Add 9 to both sides of the equation to isolate the term with y: y0y1 Divide both sides by y2 to solve for y: y4y5
