Question

solve the equations a. 6（a+6)-3a=18 b. 7k-2/3=5/3 c. 3(x+2)=4(x-3)

Answer 1

Answer:

Answers are -6 , 1/3 , 18.

Step-by-step explanation:

a) 6(a+6) -3a = 18

6a +36 -3a = 18

3a = 18 - 36

3a = -18

a = -18/3 = -6

b) 7k -2/3 = 5/3

(21k-2)/3 = 5/3

21k -2 = 5

21k = 5+2

21k =7

k = 7/21 = 1/3

c) 3(x+2) = 4(x-3)

3x + 6 = 4x - 12

6 + 12 = 4x - 3x

18 = x
