Question

Select all the equations that have no solution

A. x + 6 = 5 + x
B. -2(x - 3) = -2x + 6
C. 4 - 4x = 3x + 2
D. 4(x + 1) = 3(x + 2)
E. 5 - 3x = -3x + 4

Answer 1

A, E

Explanation:

x + 6 = 5+x can not be a solution. This is because both of the x's will cancel each other out.

5 - 3x = -3x +4 can not be a solution. The negative 3x's will cancel each other out if you try to balance both sides by doing +3x on both sides.
