Question

Simplify the expression

Answer 1

Answer:

1) $9x + 2y + 6 + 9y + 7=9x +11y+13$

2) The coefficient of y is 11.

3) The constant is 13.

Step-by-step explanation:

Given : Expression $9x + 2y + 6 + 9y + 7$

To find :

1) Simplify the expression

2) What's the coefficient of y?

3) What's the constant?

Solution :

1) $9x + 2y + 6 + 9y + 7$

Solve like terms together,

$9x + 2y + 6 + 9y + 7=9x +11y+13$

2) The coefficient is the number before any variable or multiple of any variable.

The coefficient of y is 11.

3) The constant is the number on its own.

The constant is 13.

Answer 2

First you need to combine like terms.

9x + 11y + 13

A coefficient is the number that comes before the variable (which is y).

The coefficient for y is 11.

Constants are the numbers that do not have variables attached to them.

The constant is 13.

Hope this helps!
