They are identities because they are true for ALL values of w and x.
If a equals 3 and b equals minus 5 then a minus b equals what
This cannot be solved. If you have 2 unknowns (a,b) then you must have 2 equations.
÷/÷ = +
a minus take away a minus makes a minus
In subtraction, the minuend minus the subtrahend equals the difference.
+ (plus) - (minus) / (divide) * (multiply) ^ (power) = (equals)
x = 4 and y = 7 which will satisfy both equations
{-1,-2}
No.
The system of equations 3x - 6y = 20 and 2x - 4y = 3 is inconsistent. This is because the second equation can be derived from the first by multiplying by a factor, but the constants on the right side do not match, indicating that the lines represented by these equations are parallel and do not intersect. Therefore, there is no solution to the system.

If a equals 3 and b equals minus 5 then a minus b equals what
This cannot be solved. If you have 2 unknowns (a,b) then you must have 2 equations.
The solutions are: x = -2 and y = 4
If: x-y = 4 and x-3y = 4 Then by solving the simultaneous equations: x = 4 and y = 0 So the lines intersect at (4, 0) which will be a vertical straight line
In subtraction, the minuend minus the subtrahend equals the difference.
The solutions are: x = 4, y = 2 and x = -4, y = -2
