The equation is v 9 = 14.
According to additon property of equality: If a = b, then a + c = b + c.
\ v 9 + 9 = 14 + 9 (Add 9 to each sides)
v = 14 + 9 (Additive inverse property: 9 + 9 = 0)
v = 23 (Add: 14 + 9 = 23)
\Check:
\To check the solution, substitute v = 23 in original equation.
\ v 9 = 14
23
9 = 14
14 = 14 (Subtract: 239 = 14 )
The equation is true.
\The value of v = 23.
