Question

Resolva no conjunto dos numeros reais, a equação:
3x- 3^4-x = 24

Answer 1

Resolução:

$\mathsf{3x-3^4-x=24}\\\\\mathsf{3x-81-x=24}\\\\\mathsf{2x-81=24}\\\\\mathsf{2x=24+81}\\\\\mathsf{2x=105}\\\\\boxed{\mathsf{x=\dfrac{105}{2}}}\: \: \checkmark$

Answer 2

3x - 3⁴ - x = 24
3x - x = 24 + 81
2x = 105
x = 105 / 2
x = 52,5
