Solve the equation for y 2.7 = 5.4y - 8.1x

First, you got to the answer for x which is 0.5. After you plug in that, you solve for y and that'll be 1.25. You have to take off the y to solve for the x though. So like this:

2.7 =5.4 -8.1x                                          2.7  =5.4y -8.1(0.5)
+8.1x       +8.1x                                       2.7  =5.4y -4.05
10.8x/10.8=5.4/10.8                              +4.05 =5.4y +4.05
x=0.5                                                      6.75/5.4 =5.4y/5.4
                                                                   1.25=y

I hoped that helped.

1. isolate the variable, in this case, d. subtract 35.5 on both sides of the equation.2. 52 subtracted by 35.5 is 16.53. therefore your answer would be d= 16.5this is the basics of pre algebra, isolating variable through adding, subtracting, multiplying, and dividing, if you have any other questions to ask just comment!
