A: 11x = 5y + 80

B: 9x - 15y = 120

A: 11x - 5y = 80

B: 9x - 15y = 120

A: 11x - 5y = 80

B: 3x - 5y = 40

A - B: 8x = 40

x = 5

Now we can plug that value of x into one of the original equations to solve for y:

11(5) - 5y = 80

55 - 5y = 80

-5y = 25

y = -5

Q: What is the elimination method for 11x equals 5y plus 80 and 9x-15y equals 120?

Solving by the elimination method: x = 7 and y = 2

The elimination method only works with simultaneous equations, hence another equation is needed here for it to be solvable.

Yes and it works out that x = 3 and y = 4

Solving these simultaneous equations by the elimination method:- x = 1/8 and y = 23/12

Solving the above simultaneous equations by means of the elimination method works out as x = 2 and y = 3

Double first equation: 2x + 2y = 4 Subtract this from second equation giving 5y = 5 so y = 1 and x = 1

x = 5, y = -2

Usually elimination is used on two equations and is called linear combination. You could solve for "y." That is customary. 2x+3y=1 3y=-2y+1 y=(-2/3)x+1/3
