What is the question? I don't understand please explain?
We can distribute
2(5)+2(-x)=10-2x
we get
8+10-2x=?
18-2x=?
whatever that ? is, we don't know
multiply both sides by -1
2x-18=-?
add 18 to both sides
2x=18-?
divide bth sides by 2
x=9-(?/2)
whatever the left side it, just divide it by 2 and subtract it from 9
The difference is
.
Step-by-step explanation:
Step 1:
The polynomial
is subtracted from the polynomial
.
If we write this as an equation, we get
.
To subtract the polynomials, we group up the terms based on their variables.
In this subtraction, there are two variables i.e.
and
and there is one constant term.
Step 2:
The subtraction of the
variables;
.
The subtraction of the
variables;
.
The subtraction of the constants;
.
So
.
The rule for the linear graph is y=mx
