The variables are x and y
It's 0
6y-3x-9(1-1)=6y-3x-9(0)=6y-3x-0=6y-3xOnly like terms can be simplified. A like term has the same variables, X and Y are different variables. 6y-3x cannot be simplified because they are not like terms.
4x+6y=62 -6x+6y=-18 what is the ordered pair
6y + 4.. i think
x(y - 10) + 6y
The variables in the given expression are x and y
It's 0
3x + 6y + 6x = 9x + 6y which can be factorised as 3(3x +2y)
6y-3x-9(1-1)=6y-3x-9(0)=6y-3x-0=6y-3xOnly like terms can be simplified. A like term has the same variables, X and Y are different variables. 6y-3x cannot be simplified because they are not like terms.
4x+6y=62 -6x+6y=-18 what is the ordered pair
6x + 3y + 6y - 2x = (6x - 2x) + (3y + 6y) = 4x + 9y
-6y+3 = -7y+8 -6y+7y = 8-3 y = 5
-6y + 5 = -67y=12-6y = -72-y = -12y = 12
-x+3y+6x-6y=5x-3y
That is the answer. If y is undefined, then 1+6y is as far as you can go.
A single linear equation in two variables cannot be solved: you need two independent equations.
You cannot solve 1 linear equation in 2 unknown variables. You need at least two independent equations.
