The answer is 21
Yes it is.
It is a linear equation in one variable, x.
Yes.
The solution is (x, y, z) = (2.5, 1, 2.5).
The answer is 21
Yes it is.
x + 3 = 6xx - x + 3 = 6x - x3 = 5x3/5 = 5x/53/5 = x
If the original is 2x + 3x2 + 6 + 5x3, you should rearrange the terms in order of exponent:5x3 + 3x2 + 2x + 6
It is a linear equation in one variable, x.
Yes.
It is a linear equation in a single variable, x.
The solution is (x, y, z) = (2.5, 1, 2.5).
If: 6+y =37 Then: y = 31
It works out that x = 0 and y = 3
Two solutions and they are:- x = 0 and y = 3
It is one linear equation in two unknown variables.
