Select all of the equations that have no real solution. A 5x - 1 - 2x = 3x - 7 B 6x - (x - 2) = 5x - 2 C - 3 (5x + 3) = - 15x - 9 D 10x + 4 + x = 4 + 11x - 1

Answer: All the equations have no real and evident solutions

Step-by-step explanation:

(a) 5x - 1 - 2x = 3x - 7

Collect like terms

5x - 2x - 3x = - 7 - 1

5x - 5x = - 8

x = - 8/0

x = no solution

(b) 6x - (x - 2) = 5x - 2

6x - x + 2 = 5x - 2

Gather like terms

5x - 5x = - 2 - 2

0x = - 4

x = - 4/0

x = no solution

(c). - 3 (5x + 3) = - 15x - 9

-3 x 5x - 3 x 3 = - 15x - 9

-15x - 9 = - 15x - 9

Collect like term

-15x + 15x = - 9 + 9

0 = 0

Therefore no real solutions.

(d). 10x + 4 + x = 4 + 11x - 1

Collect like terms

11x - 11x = 3 - 4

0x = - 1

x = - 1/0

x = no real solution.
