Answer 2.43
Explanation: I did the math but seriously if you want a explanation comment and i’ll explain the process
<span> 5x + 6y= -12 7) x - 5y = 0 6) x +6y = - 42 8) 4x - 7y = -21 </span>
If x equals 4hd that means 2^ is not multipication and it is subtracting but we turn that into nagitive and that will turn into a 3 just like mentioned so it is 35
3.005 x 10^7 or 10 to the seventh power. i cant type it on the computer.
