Question

a. 4. (x + 2) = 28
b. (20x + 10): 2 = 36 + 59
c. 3. (4x + 6) = 198
d. (x + 6). 9 + 19 = 181
e. 17x − 5 = 5. (2x + 1) − 3
f. 3. (x + 2) = 2. (2x + 2) + 2

Answer 1

Respuesta:

Explicación paso a paso:

a) 4(x+2) = 28

4x + 8 = 28

x = (28-8)/4

x = 5

b) (20x + 10)/2 = 95

10x + 5 = 95

x = 90/10

x = 9

c) 3(4x + 6) = 198

4x + 6 = 198/3

4x = 66 - 6

x = 60/4

x = 15

d) (x+6)9 + 19 = 181

9x + 54 = 200

9x = 200 - 54

x = 146/9

e) 17x - 5 = 10x +5 -3

17x -10x = 7

7x = 7

x = 1

f) 3x + 6 = 4x + 4 +2

3x - 4x = 0

x = 0
