Question

5x + 7 = 3x + 4 + 2x

Answer 1

This equation is a contradiction, it has no answers.

Answer 2

no solution

Explanation:

5x + 7 = 3x + 4 + 2x , that is

5x + 7 = 5x + 4 ( subtract 7 from both sides )

5x = 5x - 3 ( subtract 5x from both sides )

0 = - 3 ← not possible

this indicates the equation has no solution
