Answer:

x =6

Explanation:

To solve the system for x, substitute the value of y from the second equation into the first to get

[tex]2x+5=4x-7[/tex]

adding 7 to both sides gives

[tex]2x+12=4x[/tex]

Subtracting 2x from both sides gives

[tex]12=2x[/tex]

dividing both sides by 2 gives

[tex]x=6[/tex]

which is our answer!
