3x - 8 = 3(x - 4) + 1
Simplify each equation. Tell whether the equation has one, no, or infinite solutions.

• one, x = 5

• no solutions

• infinite solutions

• one, x = -2

What is the first step to solve this equation:
11 - 3x = 44

• Add 3 to both sides

• Subtract 11 from both sides

• Add 11 to both sides

• Divide 3 on both sides.

3x + 2(4x - 4) = 3

• 4

• 3

• 2

• 1

-y - 15 + 9y = 3y + 2 + 4y

• -17

• 17/3

• -17/3
