30 + 2w = 2 • (w - 15)
Equation at the end of step 1 :
Step 2 :
Equations which are never true :
Solve : 2 = 0
This equation has no solution.
A a non-zero constant never equals zero.
Solving a Single Variable Equation
Solve : w-15 = 0
Add 15 to both sides of the equation :
w = 15

Step-by-step explanation:
What does it say
Using the equation y=mx+c where m is the slope, we can see that the slope is -15.
since line s is parallel to line r it will have the same slope.
now we can use the point-slope form equation to determine the equation of line s.
point (10.4) is taken as (x1,y1) and the equation is (y-y1)=m(x-x1)
which gives y-4=-15(x-10)
you can solve this equation to get the final equation
