ed mod n = 1
ed = kn + 1 for integer k
so d = (kn + 1)/e for integer k.
You would take 2 and replace it for x in your other equation and solve.
This equation is unsolvable since there are two unknowns and only one equation. You would require a second equation in order to solve it.
You'd need another equation to sub in
Add 8
Can't be done unless you have another equation with the same x and y. Then you would solve for simultaneous equations.
You would take 2 and replace it for x in your other equation and solve.
You would do it it by oppisites. 3+2+4=9 which equals C.
Normally you would need the remainder of the equation to solve it. However, anything times one equals itself, so the answer (in part) is "2y". Remember, you can't solve the equation fully without finding the value of 'y', and you cannot find the value of 'y' unless you know what resides on the other side of the equal sign.
-4
This equation is unsolvable since there are two unknowns and only one equation. You would require a second equation in order to solve it.
32
You'd need another equation to sub in
Add 8
Because this equation has four variables, it would require four unique equations involving only these four variables to solve.
Can't be done unless you have another equation with the same x and y. Then you would solve for simultaneous equations.
if the equation was 7x = 42. The answer would be x = 6
None. Properties of inequalities are not that relevant when solving equalities.
