Question

Express "A number when added to its two thirds gives 20" into alinear equation in two variables ​

Answer 1

x=20

Step-by-step explanation:

it means a number= x

added to its two third=x+2/3*x

gives 20

according to question:-

x+2/3*x=20

multiplying both sides by 3:-

x+2x/3*3= 20*3

x+2x=60

3x=60

dividing both sides by 3

3x/3=60/3

x=20
