Key Questions

Answer:
An equation is a statement that two expressions are equal, so we have:
#"expression = expression"# Explanation:
An expression is a maths sentence made up of terms which can have numbers and or variables as factors.
#3x," "3x+5," "2x^25x+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,
#3x5 = 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.
