Given
To find a solution for the linear equation, the first step is to write the equation in slope-intercept form:
-Pass the x-term to the right side of the equation by applying the opposite operation to both sides of the equal sign:
-Divide both sides by -2:
Once you have expressed the equation of the line in slope-intercept form, replace it with any value for x and calculate the corresponding value of y, for example, x=2
One solution for the linear equation is x=2 and y=-6, you can check the solution by replacing the values on the original equation, with both values the result should be 8:
As you can see the values are a valid solution for the linear equation.
So the solution is:
How you do this problem is that you first find out how much the price has gone down.
Then, you divide 9.82 by the answer to your previous equation and then you have completed the question!
Ok so basically L=5+w
w=w
P=38
and A=?
well we know that P=all the four sides added so
38=2(5+w)+2w
38=10+2w+2w
38=10+4w
28=4w
w=7
so if L=w+5 then L=7+5 so L=12
A=LxW so A=12x7 A=84
