Question

Solve -9.4 > 1.7x + 4.2. I need this ASAP

Answer 1

Hello.

We are solving -9.4 > 1.7x + 4.2.

First we need to swap sides:

$1.7x + 4.2 = -9.4$

Now we need to subtract 4.2 from both sides.

1.7x + 4.2 = -9.4

        -4.2 .  -4.2

Now let's combine -4.2 + 4.2 which is 0.

We get 1.7x < -9.4 - 4.2

Now let's divide both sides by 1.7

1.7x | -13.6

1.7     1.7

x < -13.6

      1.7

So we just divided to get x < -8.

Answer 2

Answer:

$\boxed{\bold{x<-8}}$

Step By Step Explanation:

• Switch Sides

$\bold{1.7x+4.2<-9.4}$

• Multiply Both Sides by 10

$\bold{1.7x\cdot \:10+4.2\cdot \:10<-9.4\cdot \:10}$

• Refine

$\bold{17x+42<-94}$

• Subtract 42 From Both Sides

$\bold{17x+42-42<-94-42}$

• Simplify

$\bold{17x<-136}$

• Divide Both Sides By 17

$\bold{\frac{17x}{17}<\frac{-136}{17}}$

• Simplify

$\bold{x<-8}$
