Answer 1

Respuesta:

1) x=2

2) x=1

3) x=4

4) x=7

5) x=4

6) x=4/3

7) x=3

8) x=1

Explicación paso a paso:

1) 3x+8=16-3

$3x + 8 = 16 - x \\ 3x \times x = 16 - 8 \\ 4 x= 8 \\ x = \frac{8}{4} \\ x = 2$

2) 2x+2=3+x

$2x + 2 = 3 + x \\ 2x - x = 3 - 2 \\ x = 1$

3) 5x-3= 3x+5

$5x -3= 3x + 5 \\ 5x - 3x = 5 + 3\\ 2x = 8\\ x = \frac{8}{2} \\ x = 4$

4) 9x-4=8x+3

$9x - 4 = 8x + 3 \\ 9x - 8x = 3 + 4 \\ x = 7$

5)7x-5=3x+11

$7x - 5= 3x + 11 \\ 7x - 3x = 11 + 5 \\ 4x = 16 \\ x = \frac{16}{4} \\ x = 4$

6)4x+9=17-2x

$4x + 9 = 17 - 2x \\ 4x + 2x = 17 - 9 \\ 6x = 8 \\ x = \frac{8}{6} \\ x = \frac{4}{3}$

7)4x+2=2x+8

$4x + 2 = 2x + 8 \\ 4x - 2x = 8 - 2 \\ 2x = 6 \\ x = \frac{6}{2} \\ x = 3$

$3x + 2 = 3 + 2x \\ 3x - 2x = 3 - 2 \\ x = 1$
