Another straight line equation is needed such that both simultaneous equations will intersect at one point.
20
That's an equation where x = 5
It is an equation and the value of x is 8
It is a linear equation in the variable r.
No, it is an equation. n+6 is an expression.

x = 3.75
20 = 400
Better formatting is cos(2x+20)=-0.5
4(x + y - 5) = 0
An equation where x = -20
Is the equation of a straight line with slope 2 and an intercept of (0,20).
