Kala, Deandre, and Eric have a total of $119 in their wallets, Kala has $6 more than Deandre. Eric has 3 times what kala has. Ho
Tomtit [17]
Deandre = x
Kala = x + 6
Eric = 3(x+6)
x + x + 6 + 3(x+6) = 119
2x + 6 + 3x + 18 = 119
5x + 24 = 119
5x = 95, x = 19
Deandre has $19
Kala has 19 + 6 = $25
Eric has 3(25) = $75

Solving special systems<br> {y=1/2x+4<br> {-1/2x+y=-5
ryzh [129]

Answer:

no solution

Step-by-step explanation:

Given the 2 equations

y = \frac{1}{2} x + 4 → (1)

- \frac{1}{2} x + y = - 5 → (2)

Substitute y = \frac{1}{2} x + 4 into (2)

- \frac{1}{2} x + \frac{1}{2} x + 4 = - 5 , that is

4 = - 5 ← not possible

This indicates the system has no solution
