I used the substitution method.
The first equation is what I used: y=-6x+9.7
So I plugged in y in the second equation.
4x + 2(-6x+9.7)= 9.8
4x-12x+19.4=9.8
Combine like terms
-8x+19.4=9.8
Subtract 19.4 on both sides
-8x=-9.6
Divide by -8 on both sides and you get
x=1.2
If you wanted to find y use either equation and plug in for x with the value of x!
