Question

Find the value of x and y : (10y+x)-(+10x+y)=45​

Answer 1

Answer:

10y + x = 10x + y + -45

x + 10y = 10x + y + -45

x + 10y = -45 + 10x + y

x + 10y = -45 + 10x + y

x + -10x + 10y = -45 + 10x + -10x + y

x + -10x = -9x

-9x + 10y = -45 + 10x + -10x + y

-9x + 10y + -10y = -45 + y + -10y

10y + -10y = 0

-9x + 0 = -45 + y + -10y

-9x = -45 + y + -10y

y + -10y = -9y

-9x = -45 + -9y

'-9'.

x = 5 + y

x = 5 + y

Answer 2

Answer:

10y + x = 10x + y + -45

x + 10y = 10x + y + -45

x + 10y = -45 + 10x + y

x + 10y = -45 + 10x + y

x + -10x + 10y = -45 + 10x + -10x + y

x + -10x = -9x

-9x + 10y = -45 + 10x + -10x + y

-9x + 10y + -10y = -45 + y + -10y

10y + -10y = 0

-9x + 0 = -45 + y + -10y

-9x = -45 + y + -10y

y + -10y = -9y

-9x = -45 + -9y

'-9'.

x = 5 + y

x = 5 + y
