Review of Eqs and Ineqs so far...

2x + 3 = x - 7

• x=5

• x=-4

• x=1

• x=-10

7(1 - y) = -3(y - 2)

• y = 1/4

• y = 4

• y = 5

• y = -1/10

6(6v + 6) - 5 = 1 + 6v

• 1

• -1

• no solution

• all real numbers

-3 − 6(4x + 6) > -111

• x > 3
• x < 3
• x < -3
• x > -3

Choose all that apply.

What solutions satisfy the inequality: x > -3

• -3

• -5

• -1

• 10

• 4

What is the first step?

• Get absolute value alone by subtracting 5 from both sides

• Get absolute value alone by dividing by 5 on both sides

• Split into two equations

• Distribute the 5

What is the first step?

• Get the absolute value alone by dividing both sides by 5

• Drop the absolute value bars and add 7 and 5 together

• Get the absolute value alone by subtracting 5 from both sides

• Distribute the 5
