Question

I need help with three questions 1)5d-4=4-d2)-10e+15=95-30e3) 15t+17=13t+14

Answer 1

1) 5d - 4 = 4 - d
**Get d on one side => 6d - 4 = 4
**Get d alone on side => 6d = 8
**Divide by coefficient to get d =>
d= 8/6 or 4/3

2) -10e + 15 = 95 - 30e
**Get e on one side => 15 = 95 - 20e
**Get e alone on side => -80 = -20e
**Divide by coefficient to get e =>
e = -80/-20 or 4

3) 15t + 17 = 13t + 14
**Get t on one side => 2t + 17 = 14
**Get t alone on side => 2t = -3
**Divide by coefficient to get t =>
t = -3/2
