6x plus 3y minus 2x plus 5y equals 4x plus 8y.
The question is not quite clear, do you mean -6x+3y = -18 and -10+5y = -30? If so then the solution is: -10+5y= -30 5y = -30+10 5y = -20 y = -4 Substitute the value of y into the equation -6x+3y = -18: Answer: x = 1 and y = -4
It is: 6x-5y simplified

3x-3y
6x-3y
(6x - 5y) + (-3x - 4y) =6x - 5y - 3x - 4y =3x - 9y =3 (x - 3y)
6x plus 3y minus 2x plus 5y equals 4x plus 8y.
The LCM is 30xy.
4x-2y
The question is not quite clear, do you mean -6x+3y = -18 and -10+5y = -30? If so then the solution is: -10+5y= -30 5y = -30+10 5y = -20 y = -4 Substitute the value of y into the equation -6x+3y = -18: Answer: x = 1 and y = -4
It is: x-5y simplified
It is: 6x-5y simplified

3x + 6y + 6x = 9x + 6y which can be factorised as 3(3x +2y)
3x-3y
It's an algebraic expression that can be simplified to: x-5y
