3D - 2

Whats 1) 3-a/7=-2* 2)t/8-6=-12* 3) 17-s/4=-10* 4) -3d- 1.2=0.9* 5) -0.6+9(-4a)/6=-1.4* 6) 3.5x+5 - 1.5 x=8?

Show your work if you can.Thanks!

1. i'm assuming you're solving for the variables in each of these equations... 1) 3 - a/7 = -2 subtract 3 from each side -a/7 = -5 multiply each side by 7 -a = -35 multiply each side by -1 a = 35 2) t/8 - 6 = - 12 add 6 to each side t/8 = -6 multiply each side by 8 t = -48 3) 17 - s/4 = -10 subtract 17 from each side -s/4 = -27 multiply each side by 4 -s = -108 multiply each side by -1 s = 108 4) -3d - 1.2 = .9 add 1.2 to each side -3d = 2.1 divide each side by -3 d = -.7 5) -.6 + 9(-4a)/6 = -1.4 multiply out the 9 & -4 -.6 - 36a/6 = -1.4 reduce 36a/6 -.6 - 6a = -1.4 add .6 to each side -6a = -.8 divide each side by -6 a = .13333333333333 6) 3.5x + 5 - 1.5x = 8 combine like terms (x) 2x + 5 = 8 subtract 5 from each side 2x = 3 divide each side by 2 x = 3/2 good luck!
