The expression is simplified to give x + 3y -1
Algebraic expressions are the mathematical statement that we get when operations such as addition, subtraction, multiplication, division, etc. are operated upon on variables and constants.
From the information given, we have that;
7x - 6x -4y - 5 +7y + 6
collect the like terms, we get;
7x -6x - 4y +7y -5 + 6
add or subtract the like terms, we have;
x + 3y -1
