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!
