3x+4=10 To solve: 3x+4=10 3x=6 x=2

3x-2 = 2x+3 3x-2x = 3+2 x = 5

Add 5 to both sides of the equation to get rid of the - 5. -3x - 5 + 5 = -20 + 5 Solve and simplify. -3x = -15 Divide both sides of the equation by -3. x = 5

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

The given equation: =3x-4x plus 9xy-12y =3x-4x+9xy-12y =-x+9xy-12y =-x+3y(3y-4) Answer.
