Question

16. Solve 78+x=3 (mod 5).​

Answer 1

Step-by-step explanation:

Simplifying

78 = 3x

Solving

78 = 3x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-3x' to each side of the equation.

78 + -3x = 3x + -3x

Combine like terms: 3x + -3x = 0

78 + -3x = 0

Add '-78' to each side of the equation.

78 + -78 + -3x = 0 + -78

Combine like terms: 78 + -78 = 0

0 + -3x = 0 + -78

-3x = 0 + -78

Combine like terms: 0 + -78 = -78

-3x = -78

Divide each side by '-3'.

x = 26

Simplifying

x = 26
