Answer 1

Resposta:

$a.) 6X = 2x + 16 = \\ 4x = 16 \\ x = \frac{16}{4} \\ x = 4 \\ \\ b) 2x - 5=x+2 = \\ x = 7 \\ \\ c)2x + 3 = x + 6 = \\ x = 3 \\ \\ d)5X + 7 = 3X +11 \\ 2x = 7 - 11 \\ 2x = 4 \\ x = \frac{4}{2} \\ x = 2 \\ \\ e)15x -2x=x+24 \\ 12x = 24 \\ x = 2 \\ \\ f)2x-4=16-2x \\ 4x = 20 \\ x = 5 \\ \\ g)5x + 10= 10 x - 35 \\ 5x = 45 \\ x = 9$
