Question

ME AYUDAN PORFA
TIENE QUE SER CON EL PROCEDIMIENTO

X + 4 = 8

X + 2 = 10

5X = 20

4X = 8

X/2 = 6

9X + 7 = 25

4X - 5 = 23

5X + 3 = 43

3X + 2 = 14

7X - 5 = 4X + 7

12 + X - 5 = 25 - 5

Answer 1

Respuesta:

1) x + 4 = 8 ==> x = 8 — 4 ==> x=4

2) x + 2 = 10 ==> x = 10 — 2 ==> x = 8

3) 5x = 20 ==> x = 20/5 ==> x = 4

4)4x = 8 ==> x = 8/4 ==> x = 2

5) x/2 = 6 ==> x = 2 × 6 ==> x = 12

6) 9x + 7 = 25 ==> 9x = 25 — 7 ==> 9x = 18 ==> x = 18/9 ==> x = 2

7) 4x - 5 = 23 ==> 4x = 23 + 5 ==> 4x = 28 ==> x = 28/4==> x = 7

8) 5x + 3 = 43 ==> 5x = 43 — 3 ==> 5x = 40 ==> x = 40/5 ==> x = 8

9) 3x + 2 = 14 ==> 3x = 14 — 2 ==> 3x = 12 ==> x = 12/3 ==> x = 4

10) 7x - 5 = 4x + 7 ==> 7x — 4x = 5 + 7 ==> 3x = 12 ==> x = 12/3 ==> x = 4

11) 12 + x - 5 = 25 - 5 ==> x = 25 — 5 + 5 — 12 ==> x = 13
