Fill in the missing work and justification for step 2 when solving 3(x + 2) = 12.

step work justification
1 3(x + 2) = 12 given
2
3 3x + 6 − 6 = 12 − 6 subtraction property of equality
4 3x = 6 simplify
5 three times x over three equals six over three division property of equality
6 x = 2 simplify

a. 3x + 6 = 12; distributive property

b. 3x + 2 = 12; distributive property

c. 3x + 6 = 12; multiplication property of equality

d. 3x + 2 = 12; multiplication property of equality

the correct answer is option c.   3

step-by-step explanation:

points to remember

equation of the line with coordinates (x₁, y₁) and (x₂, y₂) is given by,

slope m = (y₂ - y₁)/(x₂ - x₁)

from the figure we can see a line with two coordinates given

to find the slope of given line

here   (x₁, y₁)   = (-1, -1 ) and (x₂, y₂) = (1, 5)

slope m = (y₂ - y₁)/(x₂ - x₁)

  = (5 - -1)/(1 - -1)

  = (5 + 1)/(1 + 1)

  = 6/2 = 3

therefore the correct answer is option c.   3
