Question Video: Forming Linear Equations in Two Variables Mathematics

Video Transcript

The width of a rectangle is five more than half of the length. Write an equation for the width, 𝑤, in terms of the length, 𝑙.

If the length of the rectangle is 𝑙, then half of the length will be 𝑙 divided by two or 𝑙 over two. We are told that the width is five more than this. So we need to add five to 𝑙 over two. The width 𝑤 is equal to 𝑙 over two plus five. We could use this equation to calculate the width when given the length or vice versa.
