Question

Which of the I-values satisfy the following inequality?

Answer 1

Answer:

Simplifying

x = 2x + -21

Reorder the terms:

x = -21 + 2x

Solving

x = -21 + 2x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-2x' to each side of the equation.

x + -2x = -21 + 2x + -2x

Combine like terms: x + -2x = -1x

-1x = -21 + 2x + -2x

Combine like terms: 2x + -2x = 0

-1x = -21 + 0

-1x = -21

Divide each side by '-1'.

x = 21

Simplifying

x = 21

Answer 2

Answer:

The answers are options A and B

First solve the inequality

7x < 21

Divide both sides by 7

That's

7x/7 < 21/7

x < 3

The values that satisfy the inequality are

1 and 2 since they are both less than 3

Hope this helps you.
