Answer:
<h2>x = 4</h2>
Step-by-step explanation:
Look at the picture.
We have the triangles 30° - 60° - 90° and 45° - 45° - 90°.
The sides are in proportions:
30° - 60° - 90° ⇒ 1 : √3 : 2
45° - 45° - 90° ⇒ 1 : 1 : √2

Answer:
Step-by-step explanation:
The given system of equations is 4x - 9y = 7 and -2x + 3y = 4
In this system of equations in order to eliminate the x- terms we will multiply by a number so that coefficients of x may become same.
Therefore, to eliminate the x - terms we multiply second equation by 2.
Similarly to eliminate the y-terms we will multiply the equation by a number so that coefficient of y in both the equations become same.
Therefore, we will multiply second equation by 3.
