X=Lucy´s money
y=Edy´s money
we can suggest this system of equations:
x=y+(35/100)y ⇒x=135y/100
x+y=206.8
solve by substitution method.
(135y/100)+y=206.8
Least common multiple=100
135y+100y=20680
235y=20680
y=20680/235=88
then:
x=135y/100=135(88)/100=118.8
Answer:
Lucy´s money=$118.8
Edy´s money=$88
To check:
Together, the girls have saved a total of $118.8+$88=$206.8
Lucy´s savings account has: $88+(35/100)$88=$118.8, 35% more monty than Edy´s. account. .

4^0.2x +6=43
(2^2)^0.2x +6=43
2^2*0.2x +6=43
Answer:
-3 / 2
Step-by-step explanation:
- 5x - 6 = 3x - 9
- 5x - 6 + 6 = 3 x - 9 + 6
- 5x = 3x - 3
- 5x - 3x = 3x - 3 - 3x
- 2x = - 3
- 2x / 2 = -3 / 2
- The X = -3 / 2
