The incorrect work of a student to solve an equation 2(y + 6) = 4y is shown below.
Lina20 [59]

Answer:

<h3>⇒ A. 2 should be distributed as 2y + 12, y = 6</h3>

Step-by-step explanation:

Here are the steps to solve this equation:

<u>Given:</u>

First step: 2(y+6)-4y

Use the distributive property.

<u>Distributive property:</u>

<h3>⇒ A(B+C)=AB+AC</h3>

2(y+6)

2*y=2y

2*6=12

2y+12

Isolate the term of y from one side of the equations.

2y+12=4y

Subtract by 12 from both sides.

2y+12-12=4y-12

Solve.

2y=4y-12

Then, you subtract by 4y from both sides.

2y-4y=4y-12-4y

Solve.

2y-4y=-2y

-2y=-12

Divide by -2 from both sides.

\sf{\dfrac{-2y}{-2}=\dfrac{-12}{-2}}

Solve.

Divide the numbers from left to right.

<u>Solutions:</u>

-12/-2=6

\Longrightarrow: \boxed{\sf{y=6}}

  • <u>Therefore, the correct answer is A. "2 should be distributed as 2y+12, y=6".</u>

I hope this helps. Let me know if you have any questions.

Determine if y=-2x-7 and -y=2x+13 are parallel, perpendicular, coincide or none of these
Goryan [66]
If you move the negative on the left side of the second equation over to the right side, then we can see that the equation is equivalent to y={-2x} - 13.

Remember that an equation y = mx + b represents a line with slope m and y-intercept b. Since both equations given have a slope of -2, but have different y-intercepts, they are parallel.

How many times does 1/3 go into 1/18?
Nikitich [7]

Answer: 3/18 or you can simplify it to 1/6

Step-by-step explanation: You keep 1/18 , change the division sign to multiplication  , and flip 1/3 to 3/1 so the problem goes from

1/18 / 1/3 to

1/18 * 3/1 = 1/6
