Question

Me ayudan son escuaciones lineales :(




1._ 8x + 4 = 4x

2._ 2 - 5x = 17

3._ 3 + x - 2 = 3 + 1

4._ 2K + 7 = 12 - 3K

5._ 2 (x - 1) = 1 - 6x ​

Answer 1

a)

$8x + 4 = 4x \\ 8x - 4x = - 4 \\ 4x = - 4 \\ x = - 4 \div ( + 4) \\ x = - 1$

b)

$2 - 5x = 17 \\ - 5x = 17 - 2 \\ - 5 x= 15 \\ x = 15( - 5) \\ x = - 3$
