Find the value of y when x equals 26 x+4y=54

Factor out the common term "2".

2(13x+2y) = 54

Now, divide both sides by 2.

13x + 2y = 54/2. <-- We could not divide into a whole number so it's a fraction.

Simplify 54/2 to 27.

13x + 2y = 27 <--- Since we have a whole number without a letter, we are done with that side.

Now, we subtract 2y from both sides.

13x = 27 - 2y

Divide both sides by 13.

x = 27 - 2y/13.

That would be our final answer.

Good luck on your assignment!

answer: the resulting cross section is a rectangle. solution: a plane parallel to the base of a triangular prism will intersect a cross section that is the same shape as its bases. so the cross section is a triangle.
