Solving linear equations

Linear equations are equations that has a leading degree of 1. Given the equations below;

–5x + 9 = 9

-5x = 9 - 9
-5x = 0

x = 0

For the expressions

14n = 14n + 16

0 =16

Hence the equation has no solution

For the expression

-18 = -5 - k - 13

Collect the like terms

-18 + 13 = -5 -k

-5 = -5 - k

k = 0

Hence the value of the unknown variable are 0, unknown and 0 respectively
