Let the number be x. "Three times a number increased by 10" is mathematically translated as
3x + 10
"is equal" is mathematically translated as twenty less than six times the number" is mathematically translated as
6x - 20
The whole sentence "Three times a number increased by ten is equal to twenty less than six times the number" is translated as
3x + 10 = 6x - 20
We now solve the above linear equation to find the number x
3x - 6x = - 20 - 10
- 3x = - 30
x = 10
Check answer
Three times a number increased by ten : 3 × 10 + 10 = 40
Twenty less than six times the number : 6 × 10 - 20 = 40

Answer:
- 328 / 9
Step-by-step explanation:
- 36 + ( - 4 / 9 )
= - 36 - ( 4 / 9 )
= - 36 ( 9 / 9 ) - 4 / 9
= ( - 36 x 9 ) / 9 - ( 4 / 9 )
= ( - 324 / 9 ) - ( 4 / 9 )
= ( - 324 - 4 ) / 9
= - 328 / 9
