Question

necesito desarrollar este ejercicio
∛-64:(-4)-(8-2.7)²
5X+7-X=+3

Answer 1

Desarrollar.
∛-64:(-4) - (8 - 2.7)²
∛(-4)³ :(-4) -(8-14)²
(-4): (-4) -(-6)² =
 1 - (36)
 1 - 36 =
- 35

5x +7 -x = +3
4x = 3-7
4x = - 4
x = -4/4
x = -1

Answer 2

$\sqrt[3]{-64}: (-4) - (8-2*7)^2 = \\ \\ {-4}: (-4) - (8-14)^2 = \\ \\ 1 - (-6)^2 = \\ \\ 1 - (36) = \boxed{-35}\\ \\ \\ 5x+7-x = 3 \\ \\ 4x +7 = 3 \\ \\ 4x = 3-7 \\ \\ x= \frac{-4}{4} \\ \\ \boxed{-1}$

Espero que te sirva, salu2!!!!
