<h3>What are algebraic expressions?</h3>
An algebraic expression is defined as an expression made up of variables and constants, with algebraic operations like addition, subtraction, and division.
Given the expression;
1/2 (x + 4) = 1/2x + 1

cross multiply
2(x + 1) = 2(x+ 4)
Expand the bracket
2x + 2= 2x + 8
collect like terms
2x - 2x = 8 - 2
0 = 6
Thus, simplifying the expression gives 0 = 6
