Solve the equation. Write a justification for each step.

2(x−4)=−4x+10

x = 3

Step-by-step explanation:

Start by distributing the 2:

2x - 8 = -4x + 10

Now bring all the terms with the x on the first side and all the terms without the x on the second side, them sum what you can sum:

2x + 4x = 10 + 8

6x = 18

We divide by 6:

x = 18/6 = 3

2x−8=−4x+10

2x=−4x+10+8

2x=−4x+18

2x+4x=18

6x=18

x = 18/ 6

x = 3

sorry, i don't know i just need points, i'm new here. chao

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.
