s=4w

t=w-5

s+t+w=43

4w+(w-5)+w=43

Eight times a number increased by 9 exceeds 7 times the number by 15. Find the number.

Alborosie

Turn it into math terms bit by bit. let x be "a number"

8 times a number is 8×x

increased by 9 is +9

7 times a number is 7×x

exceeds is minus

by 15 is =15

now we put it together.

$8 \times x + 9 - 7 \times x = 15$
solve
$8x + 9 - 7x = 15 \\ x + 9 = 15 \\ x = 6$
