solve for the indicated variable. include all of your work in your answer. submit your solution. P=2L+2W; for L.

We have this equation:

$P=2L+2W$

So, we need to solve this equation for L. Then we sum -2W in each member of the equation, like this:

$P-2W=2L+2W-2W$
$P-2W=2L$

Then, dividing the equation by 2:

$\frac{P-2W}{2}=L$

Finally, let's order this equation:

$L=\frac{P-2W}{2}$

Find y in terms with x <br>Help me pleaseee thank uu:)

Answer:

y = 90 -5/2 x

Step-by-step explanation:

The angle on the left equals x+3x+x = 5x

The angle on the right equals 2y

The two angles are same side interior angles which are supplementary because the lines are parallel

5x+2y = 180

Solving for y

2y = 180-5x

Divide by 2

2y/2 = 180/2 -5x/2

y = 90 -5/2 x
