2x + y = 41 how to solve for y

The answer would to plug your value for x into y = 41 - 2x to get y.

Step-by-step explanation:

If you want to solve for y, you would want y to be in terms of x.

2x + y = 41

-2x both sides

2x + y - 2x = 41 - 2x

simplify

y = 41 - 2x

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.

step-by-step explanation:

what is the question? i am guessing you are looking for the area.

to find an area, you have to do length x width.

in this case, it would be 12 ft x 4 ft = 48 sq. ft
