Question

-6x + 30 < -18. Help pls

Answer 1

Hello, hope you are having a splendid day.

-6x+30<-18

First, move all the numbers to the right, using the opposite operation:

-6x<-18-30

-6x<-48

Divide both sides by -6:

x>8

Now, if we divide both sides by a negative variable, we change the inequlaity sign.

Hope it helps.

Ask me if you have any queries.

Answer 2

Answer:

$\boxed{\boxed{\sf x>8}}$

Step-by-step explanation:

$\sf -6x\:+\:30\:<\:-18$

Subtract 30 from both sides:

• $\sf -6x+30-30<-18-30$

• $\sf -6x<-48$

Multiply both sides by -1 :

• $\sf \left(-6x\right)\left(-1\right)>\left(-48\right)\left(-1\right)$

• $\sf 6x>48$

Divide both sides by 6:

• $\sf \cfrac{6x}{6}>\cfrac{48}{6}$

• $\sf x>8$
