Question

The difference between the length and width of a rectangle is 2 units. the perimeter is 40 units. weite and solve a system of equation to determine the length and width of the rectangle. HELp me plzz

Answer 1

`The difference between the length and width is 2 units`
\[\large \color{royalblue}{L-W=2}\]

`The perimeter is 40 units`
\[\large P=2L+2W \qquad \rightarrow \qquad \color{royalblue}{40=2L+2W}\]

Ok so here is our system of equations, the two blue ones.

Answer 2

We can solve this system by one of two methods, `Substitution` or `Elimination`. Are you familiar with either of these methods? :)
