4x-3y=1
5x+4y=9
if the second equation is multiplied by 4, what should the first equation be multiplied by to eliminate the x-variable by addition?

The solution is x = - 3 2 , y = 4.

Step-by-step explanation:

You can solve the system by adding the 2 equations together. Explanation: Now that she has isolated a variable she needs to substitute into the first equation to get them in terms of one variable.

Your answer will be: 5

Reasoning: Due to the fact that when you multiplied the second equation by 4 your outcome was 20x+16y, so what you do is the same thing with the first equation but instead of 4 you multiply it by 5 to get 20x-15y. Hope this helps!

his first public project he is asked to create a small scale drawing. the garden is a right triangle with base 25m and height 30m. are you trying to solve for the last side/hypotenuse? the irrational form of the answer would be 5\sqrt{61}
