At what value of x do the graphs of the equation below intersect ?<br> 2x-y=6<br> 5x+10y=-10
Y_Kistochka [10]

Answer:

x = 2

Step-by-step explanation:

Solve the two equations simultaneously....whereby you substitute y = 2x - 6 from the above equation into the second equation...

where...; 5x + 10(2x - 6) = -10

5x + 20x - 60 = -10...then move the variables with x to one side...

5x + 20x = -10 + 60

25x = 50

;Therefore...the value of x at intersection point = 2

\left\{\begin{array}{l}4x+y=8\\6x-9y=12\end{array}\right..

Fro mthe first equation

y=8-4x.

Substitute into the second equation 8-4x instead of y:

6x-9(8-4x)=12.
