Answer:

See below

Step-by-step explanation:

7 + 15 e^(1-3x) = 10        start by subtracting 7 from both sides

15  e^(1-3x) = 3               now divide both sides by 15

e ^(1-3x) = .2                   now take the ln  of both sides

1-3x = -1.6094379          subtract 1 from both sides

-3x = = 2.6094379         divide both sides by -3

x = .869813
