What is the coefficient of the variable in the expression 4 − 3x − 7 + 6?

the coefficient of the variable in the given expression is, -3

Step-by-step explanation:

Coefficient states that a number which is used to multiply a variable.

For example:

4y

here, y is the variable and 4 is the coefficient.

As per the statement:

Given the expression:

Here, x is the variable

By definition of coefficient, we have;

⇒-3 is the coefficient

Therefore, the coefficient of the variable in the given expression is, -3

i can answer this question sweetie!

step-by-step explanation:

n=9

step-by-step explanation:

7 times a number = 7n

decreased by 13 = 7n-13

same as is =

5 times the number = 5n

increased by 5 = 5n+5

7n-13 = 5n+5

2n=18

n=9
