Question

2) Resolver y verificar las siguientes ecuaciones:
a. 7x+3=8.2 +8
$\sqrt[2]{2x} = 8 \times 2 + 8$
​

Answer 1

7x + 3 = 8 · 2 + 8

7x + 3 = 16 + 8

7x + 3 = 24

7x = 24 - 3

7x = 21

x = 21/7

x = 3

Verificamos:

7(3) + 3 = 8 · 2 + 8

7(3) + 3 = 16 + 8

7(3) + 3 = 24

7(3) = 24 - 3

7(3) = 21

(3) = 21/7

(3) = 3

---------------------------------------------------

$\sqrt[2]{2x} = 8\cdot 2+8$

$\sqrt[2]{2x} = 16+8$

$\sqrt[2]{2x} = 24$

$2x=24^{2}$

$2x=576$

$x=576/2$

$x=288$

Verificamos:

$\sqrt[2]{2(288)} =8\cdot 2+8$

$\sqrt[2]{2(288)} =16+8$

$\sqrt[2]{2(288)} =24$

$2(288)=24^{2}$

$2(288)=576$

$(288)=576/2$

$(288)=288$
