Which methods correctly solve for the varlable x in the equation 3x + 2 = 14? Select all that apply

1)First, multiply by on both sides. Then, subtract 2 from both sides.

2)First, add 2 to both sides. Then, multiply by 8 on both sides. Finally, divide both sides b

3)First, subtract 2 from both sides. Then, multiply by on both sides,

4)First, subtract 2 from both sides. Then, divide both sides by

5)First, subtract 2 from both sides. Then, multiply both sides by 8. Finally, divide both side
by 3

4) is the only correct answer

Step-by-step explanation:

answer: the price of one pound cabbage = $ 0.8

the point (10,8) represents that the cost of 10 pounds cabbage is $ 8

step-by-step explanation:

since, here is a proportional relation between the number of pounds of cabbage (x) and the price in dollars (y).

therefore, we can write,

⇒ y = k x

where k is the constant of proportionality.

now, point (5,4) is in the line.

thus, it will satisfies the above equation of line.

⇒ 4 = 5 k

⇒ k = 0.8

thus, the equation of the line is,

y = 0.8 x

a) for x = 1,

y = 0.8

therefore, the cost of one pound of cabbage is 0.8 dollars.

b) in the below graph (10,8) represents that the cost of 10 pounds of cabbage is 8 dollars.
