Answer
$3
Step-by-step explanation:
To find the x value, you want to cancel out the y terms in the equations. To do so, multiply (2x+5y=6) by 2, and (-x+2y=-3) by -5. This gives you
4x+10y=12
5x-10y=15
You can then cancel out the y terms and add the other terms from the 2 equations together to make
9x=27
You then divide 27 by 9 to get 3 as the value for x.
