18-4x=42-4x Please Help?

Question

Please Help Thanks.

Answer 1

x is undefined

Answer 2

18-4x=42-4x

since you have the same number on both sides, you can add 4x to both.

that cancels out the -4x on both sides, so it is just

18=42

those are not equal, so there is no real answer

Answer 3

18-4x=42-4x

=-4x+4x=42-18

=0=24

**There is no possible solution.

Answer 4

cannot be solved, it is not a real equation.

.

Answer 5

18-4x=45-4x

45-18= -4x+4x

27=0x

x=0

The way i did it, which i think is correct...is that you group likes together. 45 and 18 and 4x and 4x. Which is 0. So x=0

Answer 6

It is a contradiction and has no solution

Answer 7

same thing, no answer because if you add 4x to both sides, you get 18=42, which is false.

Answer 8

18-4x=42-4x

first; exchanging the left hand side and right hand side so the coefficient at both side will be the same

that is; 18 - 42 = -4x + 4x

u will get; -24 = 0

this means that your answer will be "the value of x is undefined" because -24 is not equal to 0
