The expression equivalent to (7x-5)-(3x-2) is 4x-3
An expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.
Given is an expression (7x-5)-(3x-2), we need to find an expression equivalent to it,
= (7x-5)-(3x-2)
Opening the brackets and multiply by - sign,
= 7x-5-3x+2
Combine the like terms,
= 4x-3
Hence, the expression equivalent to (7x-5)-(3x-2) is 4x-3
