Which equation is not a linear equation? question options: a) –4v + 2w = 7 b) x4= y c) x = -5 d) 2x + 3y = 5

Option b

Step-by-step explanation:

Linear equations have the following form:

Where the exponents n, m, s and h are always 0 or 1

To know which equations are nonlinear, identify among the options given, those that have exponents other than 1 or 0

Note that in option b) the exponent of the variable x is therefore the equation is nonlinear

Finally the answer is the option b
