Answer 1

Step-by-step explanation:

a. let x be the number to be finded

according to condition,

Munna has subtracted thrice the X from 50 and the result is 8 so,

3x-50=8

3x=8+50

3x=58

x=58/3

x=19.33

b. let X be the number to be finded

according to condition,

Ibenhal added 19 to her number and then divided the sum by 5 to get the result 8 so,

x+19÷5=8

x+19=8×5

x+19=40

x=40-19

x=21
