Answer 1

$\Huge\boxed{\underline{\underline{\tt{\blue{Answer !!}}}}}$

(1) 5 times a number equals 40

▪︎40 ÷ 5 = 8

(2) A number increased by 8 equals 15.

▪︎15 - 8 = 7

(3) 25 exceeds a number by 7.

▪︎25 - 7 = 18

(4) A number exceeds 5 by 3.

▪︎5 + 3 = 8

(5) 5 subtracted from thrice a number is 16.

▪︎16 + 5 + 5 + 5 = 31

(6) If 12 is subtracted from a number, the result is 24.

▪︎24 + 12 = 36

(7) Twice a number subtracted from 19 is 11.

▪︎19 - 11 = 8 ÷ 2 = 4

(8) A number divided by 8 gives 7.

▪︎8 × 7 = 56

(9) 3 less than 4 times a number is 17.

▪︎17 + 3 = 20 ÷ 4 = 5

(10) 6 times a number is 5 more than the number.

▪︎6x + 5
