Answer 1

Resposta:

a)6x=2x + 16

6x – 2x= 16

4x=16

x=16÷4

x=4

b)2x–5=x+1

2x–x=+1+5

x=6

c)2x+3=x+4

2x–x=+4–3

x=1

Answer 2

Resposta:

$A) 6x=2x +16 \\ 6x - 2x = 16 \\ 4x = 16 \\ x = \frac{16}{4} = 4$

$B)2x -5= x+1 \\ 2x - x = 1 + 5 \\ x = 6$

$C)2x +3=x +4 \\ 2x - x = 4 - 3 \\ x = 1$

$D)5x +7=4x +10 \\ 5x - 4x = 10 - 7 \\ x = 3$

$E)4x -10=2x +2 \\ 4x - 2x = 2 + 10 \\ 2x = 12 \\ x = \frac{12}{2} = 6$

$F)4x -7=8x -2 \\ 4x - 8x = - 2 + 7 \\ - 4x = 5 \\ x = - \frac{5}{ 4}$

$G)2x +1=4x -7 \\ 2x - 4x = - 7 - 1 \\ - 2x = - 8 \\ x = \frac{ - 8}{ - 2} = 4$

$H)9x +9 +3x=15 \\ 12x = 15 - 9 \\ 12x = 6 \\ x = \frac{6}{12} = \frac{1}{2}$

$I)16x -1=12x+3 \\ 16x - 12x = 3 + 1 \\ 4x = 4 \\ x = \frac{4}{4} = 1$

$J)3x -2=4x+9 \\ 3x - 4x = 9 + 2 \\ - 1x = 11 \\ x = \frac{11}{ - 1} = - 11$

$K)5x -3+x=2x+9 \\ 6x - 2x = 9 + 3 \\ 4x = 12 \\ x = \frac{12}{4} = 3$

$L)17x-7x=x+18 \\ 10x - x= 18 \\ 9x = 18 \\ x = \frac{18}{9} = 2$

$M)x+x-4=17-2x+1 \\ 2x + 2x = 17 + 1+ 4 \\ 4x = 22 \\ x = \frac{22}{4} = \frac{11}{2}$

$N)x+2x+3-5x=4x-9 \\ 3x - 5x - 4x = - 9 - 3 \\3x - 9x = - 12 \\ - 6x = - 12 \\ x \frac{ - 12}{ - 6} = 2$

$O)5x+6x-16=3x+2x-4 \\ 11x - 16 = 5x - 4 \\ 11x - 5x = - 4 + 16 \\ 6x = 12 \\ x = \frac{12}{6} = 2$

$P)5x+4=3x-2x+4 \\ 5x =1 x + 4 - 4 \\ 5x - 1x = 4 - 4 \\ 4x = 0 \\ x = \frac{0}{4} = 0$

lembrando que não existe número q dividir o 0 então o x vai ser 0.

espero ter ajudado!
