Answer:
The sum of 4 times a number and -3 added to 9 times the number is:
4x + (-3 + 9x)
Step-by-step explanation:
Determine what each of the words means
"the sum of" - you are going to be adding the following two numbers.
"4 times a number" - Let x be the number, so, 4x is the first number.
"and -3 added to" - again, it's going to be addition of this number and the following number.
"9 times the number" - let x be the number, so, 9x is the second number in the second addition.
Now that we know what it all means, put it together:
4x + (-3 + 9x)
