An equation is a statement that two expressions are equal, so we have:

#"expression = expression"#

An expression is a maths sentence made up of terms which can have numbers and or variables as factors.

#3x," "3x+5," "2x^2-5x+3# are all examples of expressions.

An equation is a statement that two expressions are equal, so we have:

#"expression = expression"#

An equation is solved, which means to find the value(s) of the variable(s) which makes the equation true,

#3x-5 = 22" "rarr x = 9#

#x^2 +4x -45 =0" "x = -9 or x=5#

An equation which contains two or more variables does not have a unique solution, but rather many, many solutions,

#x+y=10 # has infinitely many solutions.
