What is the first step you should take to solve this equation: 3(x-2) = 2x + 7

• Add 2 to both sides

• Use the distributive property to get rid of the parentheses

• Isolate the variable on one side

• Subtract 7 from both sides

Solve the equation:

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

• 4

• 3

• 2

• 1

Solve the equation \frac{1}{2}\left(4x\ -\ 8\right)\ +\ \frac{1}{2}\ =\ 1x\ +\ \frac{1}{2}

• x = 8

• x = 0

• x = 9

• x = 4

10x + 9 = 4x - 9

• 0

• 3

• -3

• -18

-5k + 10 = -2k - 14

• 8

• -8

• 2

• -2

x - 2x + 3 = 3 - x

• all real numbers

• no solution

• x = 0
