Question

Pls answer all these questions with step by step explanation they are very important

Answer 1

Answer:

a) 3x=27 x 8

therefore

x= 27 x 8

3

x= 72

b) 5x + 3 = 4 + 4x

3

3(5x + 3)= 4+4x

15x +9= 4+4x

15x-4x= 4-9

9x=-5

x= -5/9

Answer 2

Step-by-step explanation:

(a)=3x/8=27

3x=27*8

3x=216

x=216/3

x=72

(b)=5x+3=4/3(1+x)

5x+3=4+4x/3

3(5x+3)=4+4x

15x+9=4+4x

15x-4x=4-9

11x=-5

x=-5/11
