You could write-9 + 24It's equivalent to 15.
To write the expression "4 more than 6 times a number," you would start by writing the mathematical operation for "6 times a number," which is 6x. Then, you would add 4 to this result to get the final expression. Therefore, the expression can be written as 6x + 4.
78 + yz = yz + 78
The expression (a+b) + (a-b) can be rewritten as a + b + a - b = 2a.There is no need to use absolute value.
