y = 5x3 + 6 is a cubic equation, not a linear equation. Linear equations contain only terms of degree 0 (i.e. constants) and terms of degree 1.
It is a linear equation in one variable, x.
Yes.
If: 6+y =37 Then: y = 31
It is a linear equation in one unknown variable, n.
The equation 2x - 3y = 6 is a linear equation and a linear equation is always has a straight line as a graph
This is a linear equation. The value x = -1 is the solution to this equation.
It is one linear equation in two unknown variables.
y = 5x3 + 6 is a cubic equation, not a linear equation. Linear equations contain only terms of degree 0 (i.e. constants) and terms of degree 1.
It is a linear equation in one variable, x.
Yes.
It is a linear equation in a single variable, x.
If: 6+y =37 Then: y = 31
-4
It is a linear equation in one unknown variable, n.
A linear equation in 3 unknown variables cannot be solved.
Yes. You can tell by the fact that both variables are raised to the first power.
