Question

Kendall is solving this inequality.

x/2 + 6 > 42

What should she do first to solve?

a. Add 42 to both sides of the inequality.

b. Subtract 6 from both sides of the inequality.

c. Add 6 to both sides of the inequality.

d. Divide both sides of the inequality by 2.

Answer 1

Answer:

B) Subtract 6 from both sides of the inequality.

Step-by-step explanation:

By doing so, we have the following:

x/2 + 6 > 42

x/2 + 6 > 42 - 6

x/2 > 36

(x/2)*2 > 36*2

x > 72

Answer 2

Answer:

B. subtract 6 from both sides of the inequality.

Step-by-step explanation:

Kendall, when solving inequality, would isolate the variable, x.

The first step will be to subtract 6 from both sides of the inequality:

$\frac{x}{2} + 6 > 42\\\frac{x}{2} + 6 (-6) > 42 (-6)\\\frac{x}{2} > 36$

The next step will be to multiply 2 to both sides of the inequality:

$\frac{x}{2} > 36\\\frac{x}{2} *2 > 36 *2\\x > 36 * 2\\x > 72$

x > 72 would be the answer.
