Mei wants to solve the inequality --W < 12. How can she isolate the variable?
2
• Multiply both sides by -2 and reverse the inequality symbol.
• Multiply both sides by -2 and do not reverse the inequality symbol.
*) Divide both sides by 12 and reverse the inequality symbol.
) Divide both sides by 12 and do not reverse the inequality symbol.

Answer 1

Answer:

Multiply both sides by -2 and reverse the inequality symbol.

Step-by-step explanation:

To isolate w, multiply both sides by the reverse of -1/2 (because -1/2*2=1 ), which is -2

When multiplying or dividing by negatives, you must reverse the inequality symbol as well.

Answer 2

To isolate the variable,  you multiply both sides by -2 and reverse the inequality symbol.

Isolating variables in inequality

Isolation of variables means making the variable the subject of the formula from the given expression.

Given the inequality expression -1/2 w  < 12

To make w the subject of the formula, we will have to multiply both sides by -2 to have;

-1/2 w * -2 >  12 * -2
w > -24

Hence to isolate the variable,  you multiply both sides by -2 and reverse the inequality symbol.
