Which statement about this equation is true?

Viktor [21]

The equation has no solution because:

5(n+10)=5n+10n
5n+10n=5n+10n
I subtract 5n from both sides
10n=10n
Only one side is supposed to have the variable which is n, so the equation has no solution.

Left to Right

Algebra I

Coordinates (x, y)
Slope Formula: $\displaystyle m=\frac{y_2-y_1}{x_2-x_1}$

Step-by-step explanation:

Step 1: Define

Point (5, 9)

Point (-3, 9)

Step 2: Identify

x₁ = 5, y = 9

x₂ = -3. y = 9

Step 3: Find slope m

Simply plug in the 2 coordinates into the slope formula to find slope m

Substitute in points [Slope Formula]: $\displaystyle m=\frac{9-9}{-3-5}$
[Slope] [Fraction] Subtract: $\displaystyle m=\frac{0}{-8}$
[Slope] [Fraction] Divide: $\displaystyle m=0$
