Expression is a mathematical phrase which combines, numbers, variables and operators to show the value of something. An equation is a mathematical statement wherein two expressions are set equal to each other.
Expressions are mathematical "phrases" containing numbers, variables, or both, while equations are mathematical "sentences" that indicate two equal or unequal expressions. You may observe on the table given, under the column of the Equations, is the "equal" (=) sign. This sign is an indication that we can solve for the value of the variable, given that we have a complete "sentence" and the expression tells us what the variable is. In general, isolating the variable using the inverse operation and substituting its value into the expression will solve the equation.
