Math Problem Statement

Select the choice that represents the two-variable inequality after it has been solved for y in terms of x. -6y < -3(y - 2x)

Solution

Let's solve the inequality step by step. We need to solve for yy in terms of xx.

The inequality is:

6y<3(y2x)-6y < -3(y - 2x)

Step 1: Distribute the 3-3 on the right side of the inequality.

6y<3y+6x-6y < -3y + 6x

Step 2: Move all terms involving yy to the left side of the inequality. Add 3y3y to both sides:

6y+3y<6x-6y + 3y < 6x

3y<6x-3y < 6x

Step 3: Solve for yy by dividing both sides by 3-3. Since we are dividing by a negative number, the direction of the inequality flips:

y>2xy > -2x

Thus, the inequality in terms of yy is:

y>2xy > -2x
