Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
The expression 7x = 42 for the value of x will be solved as below:-
7x = 42
x = 42 / 7
x = 6
Therefore, the value of x will be equal to 42.
