Multiple Choice

After collecting the variables on the left side of the equation, the coefficient of the x term will be?

[line 1] 5x + 7(x - 3) = 9x + 2 - 4x

[line 2] 5x + 7x - 21 = 5x + 2

[line 3] 12x - 21 = 5x - 2

[line 4] what is the coefficient of the x term?

• 12

• 7

• 17

• 5

Multiple Choice

When solving for the value of x in the equation , Samir wrote the following lines:

[line 1] 5x + 7(x - 3) = 9x + 2 - 4x

[line 2] 5x + 7x - 21 = 5x + 2

[line 3] 12x - 21 = 5x - 2

[line 4] 7x - 21 = -2

[line 5] What should Samir do next to isolate the variable?

• collect the constants by adding 2 to each side

• collect the constants by adding 21 to each side

• subtract 7x from each side

• divide each side of the equation by 7
