Answer:
A
Step-by-step explanation:
Replace y with x.
Solve for y.
This is the problem I’m having trouble with. It’s the first time I’ve done linear equations in four variables and I got the answ
ers x= -86 y = 237 z = 106 and w= -35 these seem like really weird answers to me. Could you tell me if these are correct and if not explain the answer?

Consider the equation , it can be expressed as
.
Now, we have to write the equivalent equation.
Since, Equivalent equations are those equations which have exactly same solution. We can say that the two equations are equivalent if solution of one equation is the solution of other equation.
So, consider the equation
Equivalent equation can be obtained by multiplying the given equation by any number say '2'.
Multiplying both sides of the given equation by '2'.
is the required equivalent equation.
