Why does 10x-1=10x+4 has no solution

Simplifying

10x + 1 = 10x + -4

Reorder the terms:

1 + 10x = 10x + -4

Reorder the terms:

1 + 10x = -4 + 10x

Add '-10x' to each side of the equation.

1 + 10x + -10x = -4 + 10x + -10x

Combine like terms: 10x + -10x = 0

1 + 0 = -4 + 10x + -10x

1 = -4 + 10x + -10x

Combine like terms: 10x + -10x = 0

1 = -4 + 0

1 = -4

Solving

1 = -4

Couldn't find a variable to solve for.

This equation is invalid, the left and right sides are not equal, therefore there is no solution.

Step-by-step explanation:

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%
