Question

In Exercises 19-24, solve the equation. Determine

whether the equation has one solution, no solution, or
infinitely many solutions. (See Example 3.)
19. 3t+ 4 = 12 + 3t
20. 6d+ 8 = 14 + 3d
21. 2(h+ 1) = 5h - 7
22. 12y + 6 = 6(2y + 1)
23. 3(4g + 6) = 2(6g + 9)
24.
5(1+2m)=(8 + 20m)

Answer 1

Explanation:

Given is a linear equation in t



If we want to simplify we find that 3t gets cancelled and we get



This is an impossible situation.

This implies that original equation has no solution at all

Hence answer is

the given has no solution
