9.8488578018 That is the answer
I’m pretty sure the answer is B because
8X- 4Y = -16 and it shows that in the equation of number B and if I’m wrong please correct me
12x+12 because you do the distribution property and this is how 3*9=27 3*4x=12x 3*-5=-15 27-15 = 12 so 12x+12 would be the answer it is really simple.
For this you want to solve a 2-step equation
0.5x+4.2=5.9
subtract 4.2 from the left and right sides
then divide on the left and right sides
x=3.4 (option B)
