This inequality has NO SOLUTION:

PROOF:

3x + 1 < 2x - 2 < 5x +7

1st let's analyze the 1st inequality: 3x+1<2x-2
3x-2x <-2-1 Then x <-3

2nd let's analyze the 2nd inequality: 2x-2 < 5x+7
2x-5x < 7+2 Then -3x<9 OR 3x > - 9 and x> - 3

In the 1st we have x <-3 in the 2nd we have x > - 3 which is impossible

Solve this equation: 5/8y=-1

djverab [1.8K]

$\frac{5}{8} y = -1$

First, change $\frac{5}{8} y$ to $\frac{5y}{8}$ / Your problem should look like: $\frac{5y}{8} = -1$
Second, multiply both sides by 8. / Your problem should look like: $5y = -8$
Third, divide both sides by 5. / Your problem should look like: $y = -\frac{8}{5}$

Answer as fraction: y = $- \frac{8}{5}$
Answer as decimal: -1.6
