Question

cual es la respuesta a esta ecuacion 3x-8x=35 y esta 2(2x+5)=45

Answer 1

3x - 8x = 35

-5x = 35

x = 35/-5

x = -7

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

2(2x+5) = 45

4x + 10 = 45

4x = 45 -10

4x = 35

x = 35/4

Answer 2

$3x - 8x = 35 \\ \\ -5x = 35 \\ \\ x = - 7$
$2(2x + 5) = 45 \\ \\ 4x + 10 = 45 \\ \\ 4x = 45 - 10 \\ \\ 4x = 35 \\ \\ x = \frac{35}{4} \\ \\ x = 8.75$
