Question

Simplify the expression;

7y + 4x + 4 - 2x + 8
what is the coefficient of X?
what is the constant?

Answer 1

4-2= 2, coefficient of x =2

Answer 2

`7y+2x+12`

Coefficient of x=2

Constant term=12

Explanation:

We are given that an expression

`7y+4x+4-2x+8`

We have to simplify the expression and find the coefficient of x and constant term.

Combine like terms then we get

`7y+2x+12`

It is compared with the equation of two variables

`ax+by+c=0`

Where a= Coefficient of x

b=Coefficient of y

c= Constant term

Then, we get

a=2,b=7,c=12

Coefficient of x,a=2

Constant term,c=12
