Answer:
1.25 × 10^-4
Step-by-step explanation:
Move the decimal until it's at 1.25. You had to go right 4 times so it's negative. If it were 12500 then you'd do it until it was 1.2500 which would be going left so it'd be a positive 4
First you solve 2y-3y=9.

Now that you have y, then you substitute y into x-2y=3 to find X

Your solution is (-15, -9)
