Hi there!

[tex]\large\boxed{x = 2.5}[/tex]

We can solve for x by using an elimination of variables.

2x + 5y = 20

-2x + 10y = 25

Add the two equations to eliminate x:

0x + 15y = 45

15y = 45

y = 3

Substitute this value of y into an equation to solve for x:

2x + 5(3) = 20

2x + 15 = 20

2x = 5

x = 2.5
