It is a linear equation in one variable, x.
The solution is (x, y, z) = (2.5, 1, 2.5).
It works out that x = 0 and y = 3
Yes, y = 3+x is linear.
2x+3y = 6 2x+3(0) = 6 2x = 6 x = 6/2 x = 3
It is a linear equation in one variable, x.
The solution is (x, y, z) = (2.5, 1, 2.5).
It is a linear equation in a single variable, x.
It works out that x = 0 and y = 3
Yes, y = 3+x is linear.
2x+3y = 6 2x+3(0) = 6 2x = 6 x = 6/2 x = 3
Two solutions and they are:- x = 0 and y = 3
no
Two equations: a linear one in y and a quadratic in x.
Only if it's a function.
It is a linear equation in x. It has a solution, which is x = -5
Yes, y=-2+x is a linear function.
