Answer:

The equation is invalid.

Step-by-step explanation:

Simplifying:

28 + 8x = 8(x + 3) + 2

Reorder the terms:

28 + 8x = 8(3 + x) + 2

28 + 8x = (3 * 8 + x * 8) + 2

28 + 8x = (24 + 8x) + 2

Reorder the terms:

28 + 8x = 24 + 2 + 8x

Combine like terms: 24 + 2 = 26

28 + 8x = 26 + 8x

Add '-8x' to each side of the equation.

28 + 8x + -8x = 26 + 8x + -8x

Combine like terms: 8x + -8x = 0

28 + 0 = 26 + 8x + -8x

28 = 26 + 8x + -8x

Combine like terms: 8x + -8x = 0

28 = 26 + 0

28 = 26

Solving:

28 = 26

The left and right sides are not equal! Meaning theres no solution.

Answer:

No Solutions

Step-by-step explanation:

10 - 4(3-2y) = 8y - 5

Distribute:

10 - 12 + 8y = 8y - 5

Simplify:

-2 + 8y = 8y - 5

Same to both sides

-2 + 5 = 8y - 8y

3 = 0y

Answer:

Step-by-step explanation:

The constant of proportionality is the ratio between the two proportional variables in a directly proportional relationship. In this case, the variables are $x$ and $y$ .

To find the constant of proportionality, all we have to do is divide any value of $y$ by its corresponding value of $x$ . Let's take the values in the first row of the table. We know that $x=2$ and $y=12$ , so the constant of proportionality is $\frac{y}{x}=\frac{12}{2} =6$ . Hope this helps!
