Simplify the expression

2x+10

Step-by-step explanation:

(9x^2+27x-3x^2+3x)/3x

(3x^2+9x-1x^2+1x)/x

3x^2 - 1x^2= 2x^2

9x+1x=10x

2x^2+10x/x

when you divide you subtract exponents

x^2-x^1 = x   x^1- x^1= x^0=1

2x+10

3+x

step-by-step explanation:

system of linear equation

step-by-step explanation:

as given in the data

a= 20 , b= -12

let us suppose that it is a straight line equation

now we know the formula for the system of linear equation

b= ma + c )

here m is slope of a straight line which is equal to formula

m=   (ii)

and here c is a constant

now putting the value of a and b in equation (ii)

m=

m=

putting the value of a,b and m in equation (i) gives us

-12 = + c

-12=-12 + c

adding 12 to both sides

-12 +12 = -12 +12 +c

0 =c

or c=0

as the value of the constant is zero which gives us that it is a linear equation and this order pair satisfies the system of linear equations.
