Fill in the blanks to make the statements true. In natural numbers, 4x + 5 = -7 has _______ solution.

Answer»

Consider the given integers, 4x + 5 = – 7.

Transpose 5 to RHS then it becomes -5.

4x = – 7 – 5

4x = – 12

x = -12/4 = -3

In natural numbers, 4x + 5 = – 7 has no solution.

it has 1 solution

taking 5 on  LHS to RHS

we get, 4x= -12

therefore x = -3
