What is the value of n in the equation 3n + 2(n + 2) = 9n + 12?

−4
−2
2
4

The work of a student trying to solve the equation 2(2x − 3) = 6 + 2x + 4 is shown below:

Step 1: 2(2x − 3) = 6 + 2x + 4

Step 2: 4x − 3 = 10 + 2x

Step 3: 4x − 2x = 10 + 3

Step 4: 2x = 13

Step 5: x = 6.5

In which step did the student first make an error and what is the correct step?

Step 2: 4x − 6 = 10 + 2x

Step 2: 4x − 3 = 2 + 2x

Step 3: 4x + 2x = 10 + 3

Step 3: 4x − 2x = 10 - 3

Step-by-step explanation:

75

step-by-step explanation:

you do x-29=46 (the number of cantaloupes sold)

in order to find x, you have to find what minus 29 equals 46, meaning you'd have to add 29 to 46.

29+46=75

if you replace x with 75, the equation looks like:

75-29=46

x=75

both graphs increase on their domain

neither graph has a y-intercept
