Answer:

x + 1 = 4x + 5

Step-by-step explanation:

To solve this set of equation you can just equalize them ot one another, as you can see they are already in Y form, which means that they have already been solved for Y, so that makes things easier for us, we just insert the second equation in the place of Y in the first one, and we can solve for "x".

Answer:

<h2>Width of the rectangle is 2</h2>

Step-by-step explanation:

A rectangle can is made up of two right angled triangle as shown.

Since area of a rectangle = $base * height$

Area of one of the triangle = $\frac{1}{2}\ * \ area\ of\ the\ rectangle$

The length and width of the triangle will be the same as that of the rectangle i.e 5units long and 2units wide

Area of one of the triangle = $\frac{1}{2} * 5 * 2$

Area of one of the triangle = 5units²

The area of the triangle above will equal one half of a rectangle that is 5 units long and 2 units wide.
