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

x = 3 and y = 3 Form a simultaneous equation and solve by elimination.

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

x = 3 and y = 3 Form a simultaneous equation and solve by elimination.

2x + 2y = 44x + y = 1There are many methods you can use to solve this system of equations (graphing, elimination, substitution, matrices)...but no matter what method you use, you should get x = -1/3 and y = 7/3.

Solving by the elimination method: x = 7 and 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

You cannot solve one linear equation in two variables. You need two equations that are independent.

(A) x + 6y = 19 (B) -x + 6y = 17 (A)+(B): 12y = 36 so that y = 3 Substituting this value of y in (A), x + 18 = 19 so x = 1.
