Hello!
That problem looks pretty messy... let's clean it up! :D
so we have this -----> -0.3(0.7x - 0.9) = -1.83 let's get simplifying
-0.21x + 0.27 = -1.83 -----> I distributed the -0.3 among 0.7x and -0.9
-0.21x = -2.1 -----> I subtracted 0.27 on both sides of the equation
<u>x = 10</u><u /> -----> I divided -0.21 on both sides of the equation
The answer you're looking for is D!
I hope this helps! :D
