b) 2x − 5 = x + 1
c) 2x + 3 = x + 4
d) 5x + 7 = 4x + 10
e) 4x − 10 = 2x + 2
f) 4x − 7 = 8x − 2
g) 2x + 1 = 4x − 7
h) 9x + 9 + 3x = 15
i) 16x − 1 = 12x + 3
j) 3x − 2 = 4x + 9
k) 5x − 3 + x = 2x + 9
l) 17x − 7x = x + 18
m) x + x − 4 = 17 − 2x + 1
n) x + 2x + 3 − 5x = 4x − 9
o) 5x + 6x − 16 = 3x + 2x − 4
p) 5x + 4 = 3x − 2x + 4

Answer 1

Claro Que Eu Vou Te Ajudar Mas Vai Ser  Da A  Ate a  D

a) 6x = 2x + 16

$\\6x=2x+16\quad :\quad x=4\\\\6x-2x=2x+16-2x\\\\\frac{4x}{4}=\frac{16}{4}\\\\x=4$

b) 2x − 5 = x + 1

$2x-5=x+1\quad :\quad x=6\\\\2x-5+5=x+1+5\\\\2x-x=x+6-x\\\\X=6$

c) 2x + 3 = x + 4

$2x+3=x+4\quad :\quad x=1\\\\2x+3-3=x+4-3\\\\2x-x=x+1-x\\\\x=1$

d) 5x + 7 = 4x + 10

$5x+7=4x+10\quad :\quad x=3\\\\5x+7-7=4x+10-7\\\\5x-4x=4x+3-4x]\\\\x=3$
