Question

RESOLVA EQUAÇOES DO PRIMEIRO GRAU 5X+7=9X+2X-6 2X+4=-3X+35 2X+4= -X+22 2X+4= -5X-10

Answer 1

5X+7=9X+2X-6
7+6= 11X -5X
13= 6X
$\frac{13}{6}$=X
X=$\frac{13}{6}$

2X+4=-3X+35
2X+3X= 35 -4
5X=31
X= $\frac{31}{5}$


2X+4= -X+22
2X+X= 22-4
3X= 18
X=$\frac{18}{3}$
X=6


2X+4= -5X-10
2X+5X= -10-4
7X = -14
X= $\frac{-14}{7}$
X= -2
