Question

Solve the following : 9.8x-13.8=2.7=1÷5x

Answer 1

firstly,

9.8x-13.8=2.7

9.8x=16.5

x=165/98

secondly,

2.7=1/5x

27*5x/10=1

27x/2=1

27x=2

x=2/27

can you tell me whats going on here

Answer 2

9.8x - 13.8 = 2.7 = 1÷5x

(first arrange it in order)

= 9.8x ×5x = 2.7 + 13.8 -1

(now solve it in order one by one)

= 49x = 16.5 -1

= 49x = 15.5

(now find the value of x)

= x = 155/ 49×10 (removed point by multiplying it by 10)

= x= 31/98
