Describe a "legal move" when you are solving an equation.

Ok, let me start by taking an equation in one variable

Now , If we multiply by any integer on both side of the equation ,the solution of the equation does not change.

Now consider equation in two variable

now if you multiply by any integer on both side of the equation, we are not getting solution of the equation but it maintains the equality on both sides.

So, finally the meaning of legal move is that we are not getting the solution of linear equation by multiplying with any integer it just maintains the balance on both side without affecting the answer.

9.55 degrees.

step-by-step explanation:

the given angle is

1 cycle is equal to 2π radians. so 4π will be equal to two cycles.

5.166667π-4π = 1.166667π

hence, this angle goes a little more than negative x axis.

1.166667π-π= 0.166667π

hence, the reference angle is 0.166667π radians.

1 radian = 57.2958 degrees

now, in degrees, this should be equals to 9.55 degrees.

answer: 0+0=0

step-by-step explanation:

that is the only answer that can make 0
