Question

please. Following system of equation using the elimination method and answer the value of x 2 x + 5y equals to 5x + 10 y equals 17

Answer 1

we are given the following system of equations:

$\begin{gathered} 2x+5y=2,(1) \\ 5x+10y=17,(2) \end{gathered}$

Now we multiply equation (1) by -2, we get:

$-4x-10y=-4$

Now we will add this equation to equation (2):

$(5x+10y)+(-4x-10y)=17-4$

Adding like terms:

$x=13$
