Answer:
X = [tex]\frac{18}{5}[/tex], or X = 3.6
Step-by-step 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=[tex]\frac{18}{5}[/tex], x=3.6
8/5 or 3.6
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
