Describe the steps for simplifying the expression 2x + 3 + 5x – 15.​

Step-by-step explanation:

2x+3+5x-15

I can start off by combining like terms (2x and 5x with 3 and -15)

2x+5x+3-15

and my new equation will be 7x-12. Since they are not like terms (15 does not have x so I can't continue solving), 7x-15 will be my final answer.

Group and add the x coefficients (factoring)

Add the other numbers: 3 and -15

2x + 3 + 5x – 15 = 2x + 5x + 3 – 15 = 7x - 12

Step-by-step explanation:

in mathematics, a function is a relationship between two variables such that the value of one of the variables, called the dependent variable, is determined by the value of the other variable, called the independent variable. there is a specific term we use to describe the set of independent variables of a function.

the answer is b.

step-by-step explanation:

identity property is where 0+whatever number=whatever number. basically 0+ a number.
