Solve the equation for the indicated variable.
-$P = S _ { 1 } + S _ { 2 } + S _ { 3 } , \text { for } S _ { 3 }$
A) $\mathrm { S } _ { 3 } = \mathrm { S } _ { 1 } + \mathrm { S } _ { 2 } - \mathrm { P }$
B) $\mathrm { S } _ { 3 } = \mathrm { P } - \mathrm { S } _ { 1 } - \mathrm { S } _ { 2 }$
C) $\mathrm { S } _ { 3 } = \mathrm { S } _ { 1 } + \mathrm { P } - \mathrm { S } _ { 2 }$
D) $\mathrm { S } _ { 3 } = \mathrm { P } + \mathrm { S } _ { 1 } + \mathrm { S } _ { 2 }$
