Question

A certain no. is increaced by 5 and one half of the result is equal to two fifth of the no. reduced from 85. then the no. is?​

Answer 1

Answer:

equation for the expression is

1/5 (x+5) = 85-2/5x

1/5x+5/5=85-2/5x

5/5-85= -2/5x -1/5x

5-425/5=-2x-1x/5

5-425=-2x-1x

-420=-3x

-420/-3=x

140=x

the answer is 140

STEP BY STEP EXPLANATION :

FIRSTLY WE WILL FORM THE NUMERICAL EXPRESSION FOR THE WRITTEN EXPRESSION. THEN AFTER THAT, WE WILL SOLVE THE BRACKET.

THEN WE WILL GET THE CONSTANTS ON ONE SIDE BY CHANGING THEIR SIDES AND SIGNS.

AFTER THAT WE WILL SOLVE IT BY MULTIPLYING,CANCELLING THE SAME DENOMINATORS AND WE WILL GET THE ANSWER THAT IS 140.
