Given the equation, 7x + 5 = 2(4x + 3):

Distribute 2 into the terms inside the parenthesis:

7x + 5 = 2(4x + 3)
7x + 5 = 8x + 6

Subtract 5 from both sides:

7x + 5 - 5 = 8x + 6 - 5

7x = 8x + 1

Then, subtract 8x from both sides:

7x - 8x = 8x + 1 - 8x

- x = 1

Finally, divide both sides by -1 to solve for x:

-x / -1 = 1 / -1

x = -1

Therefore, the solution to the given equation is -1.

Answer:

Step-by-step explanation:

There's 24 students so I would do 5 × 24 which equals 120 so 420 - 120 is 300. Then 2 × 24 is 48. Now 300-48 is 252. They would have $252 left.

Answer:

B. y= -4x + 28

Step-by-step explanation:

To find the equation of this line first put it into slope-point form, $y-y_{1} =m(x-x_{1})$ where $y_{1}$ and $x_{1}$ are the y and x coordinates and m is the slope. So plug in the information to get the equation, y-8=-4(x-5). Then solve for y,
