Set up equations and solve them to find the unknown numbers in thefoll

1.	Set up equations and solve them to find the unknown numbers in thefollowing cases:(a) Add 4 to eight times a number; you get 60.(b) One-fifth of a number minus 4 gives 3.(c) If I take three-fourths of a number and add 3 to it, I get 21.(d) When I subtracted 11 from twice a number, the result was 15.(e) Munna subtracts thrice the number of notebooks he has from 50, hefinds the result to be 8.(f) Ibenhal thinks of a number. If she adds 19 to it and divides thesum by 5, she will get 8.(g) Anwar thinks of a number. If he takes away 7 from ofthe number, the result is 23.

Answer»

Set up equations and solve them to find the unknown numbers in the
following cases:

(a) Add 4 to eight times a number; you get 60.

(b) One-fifth of a number minus 4 gives 3.

(d) When I subtracted 11 from twice a number, the result was 15.

(e) Munna subtracts thrice the number of notebooks he has from 50, he
finds the result to be 8.

(f) Ibenhal thinks of a number. If she adds 19 to it and divides the
sum by 5, she will get 8.

(g) Anwar thinks of a number. If he takes away 7 from
of
the number, the result is 23.
