The simplified form of the expressions are 69-y/16 and -x/3 - 27 respectively
Solving algebraic equation
An algebraic equation can be defined as a mathematical statement in which two expressions are set equal to each other.
Given the following algebras
5-y/16 + 4
Find the LCM
5-y+4(16)/16
5-y+64/16
69-y/16
Hence the simplified form of the equation is 69-y/16
For the algebraic equation -3(x/8 + 9)
Expand
-3(x/8) + -3(9)
-3x/9 - 27
-x/3 - 27
Hence the simplified form of the expression is -x/3 - 27
