Question

Which of the following values are solutions to the inequality 9 ≤ -7+ 4x?

I. - 4
II. O
III. 4

Answer 1

Answer: Inequality Form: x ≥ 4

lll. 4

Explanation:

Isolate the variable by dividing each side by factors that don't contain the variable.

Answer 2

Your answer is x ≥ 4

Explanation:

a) Simplify both sides of the inequality.

9 ≤ 4x − 7

b) Flip the equation.

4x − 7 ≥ 9

c) Add 7 to both sides.

4x − 7 + 7 ≥ 9 + 7

4x ≥ 16

d) Divide both sides by 4.

4x/4 ≥ 14/4

x ≥ 4
