A student solved 3/x−4=x/7 in six steps, as shown.

Stolb23 [73]

Answer:

Option A.

Step-by-step explanation:

The given equation is

$\dfrac{3}{x-4}=\dfrac{x}{7}$

Step 1: Multiply both sides by (x-4).

$3=\dfrac{x(x-4)}{7}$

Step 2: Multiply both sides by 7.

$21=x(x-4)$

Step 3: Using distributive property.

$21=x^2-4x$

Step 4: Isolate all terms on one side.

$0=x^2-4x-21$

Step 5: Find factors by splitting the middle term.

$0=x^2-7x+3x-21$

$0=x(x-7)+3(x-7)$

$0=(x-7)(x+3)$

Step 6: Using zero product property, we get

$x=-3, x=7$

It means student solved the equation correctly.

Therefore, the correct option is A.

Two brothers are saving money to buy tickets to a concert their combined savings is 55. one brother has 15 more than the other.

ser-zykov [4K]

Let the amount saved by the brother that has less savings be x, then the savings of the other brother is x + 15.

Since their total savings is 55, then
x + x + 15 = 55
2x + 15 = 55
2x = 55 - 15 = 40
x = 40 / 2 = 20

Therefore, one person saved 20 and the other saved 20 + 15 = 35.
