Question

What value of × is in the solution set of -5×-15>10+20×

Answer 1

Answer:
`x<-1`

Explanation:

`-5x-15>10+20x`

Subtract 20x

`-5x-20x-15>10`

add 15

`-5x-20x>10+15`

Combine like terms

`-25x>25\\`

Divide by -25 (NOTE: When dividing or multiplying by negative numbers the inequality sign flips.)

`x<(25)/(-25)\\ x<-1`
