Question

Which is a correct first step in solving 5- 2x < 8x - 3?​

Answer 1

x>4/5

Explanation:

Subtract by 5 from both sides of equation.

5-2x-5<8x-3-5

Simplify.

-2x<8x-8

Subtract by 8x from both sides of equation.

-2x-8x<8x-8-8x

Simplify.

-10x<-8

Multiply by -1 from both sides of equation.

(-10x)(-1)>(-8)(-1)

Simplify.

10x>8

Divide by 10 from both sides of equation.

10x/10>8/10

Simplify, to find the answer.

8/10=4/5

x>4/5 is the correct answer.

I hope this helps you, and have a wonderful day!

Answer 2

Isolating the x.

Explanation:

The first step to solving this problem is to isolate the variable, x.

To do so, subtract 8x and 5 from both sides.

Step #1)

5 - 2x < 8x - 3

5 (-5) - 2x (-8x) < 8x (-8x) - 3 (-5)

-2x - 8x < -3 - 5

-10x < -8
