Ten less than a number is three more than six times the number

Mathematics

Answer:

x-10=6x+3

Step-by-step explanation:

Okay, Is means equals. I used x as the unknown number. 10 less than a number means x-10. Squishing a variable and constant ( x and 6) together means multiplication (Constant always going before the variable) It's three more than six times the number, so it's six times the number plus three.

Hope I helped :)
