# Resolvemos

$3x+2=5x-2 \\ 3x - 5x = - 2 - 2 \\ - 2x = - 4 \\ \frac{ - 2x}{ - 2} = \frac{ - 4}{ - 2} \\ x = 2$

$4x-1=x+8 \\ 4x - x = 8 + 1 \\ 3x = 9 \\ \frac{3x}{3} = \frac{9}{3} \\ x= 3$

$10x+1=3x+2 \\ 10x - 3x = 2 - 1 \\ 7x = 1 \\ \frac{7x}{7} = \frac{1}{7} \\ x = \frac{1}{7}$

$2x-5=3x \\ 2x - 3x = 5 \\ - x = 5 \\ x = - 5$

$4x - 10=-5x \\ 4x + 5x= - 10 \\ 9x = - 10 \\ \frac{9x}{9} = \frac{10}{9} \\ x = \frac{10}{9}$
