Answer:
-2.59 = x
Step-by-step explanation:
3+5.25 = 1 - 2.8x
Combine like terms
8.25 = 1-2.8x
Subtract 1 from each side
8.25 -1 = 1-1-2.8x
7.25 = -2.8x
Divide each side by -2.8
7.25/-2.8 = -2.8x/-2.8
-2.589285714 = x
Rounding
x=-2.59
423.6 is the correct answer

The answer would be 64/9. I did this by squaring each number so 8^2 and 3^2 should give me 8*8 which is 64 and 3*3 which is 9. I hope this helped you!
