Answer:

8/5 or 3.6

Explanation:

1.03x + 3.97x = 5x

So in this equation, it would be:

5x - 5 = 13

Subtract 5 from both side:

5x + 5 - 5 = 13 + 5

5x + 0 = 18

5x = 18

Divide both side by 5

5x/5 = 18/5

1x = 18/5

x = 18/5 or 3.6

Hope this help you :3

Answer:

X =
(18)/(5), or X = 3.6

Explanation:

For this problem we must isolate x

1.03x+3.97x-5=13 | Add 5 to both sides

1.03x+3.97x=18 | Add the x's

5x=18 | Now divide both sides by 5

x=
(18)/(5), x=3.6
