Fill in the blanks: An equation is a statement that the two expressions are …….
Hint: First we have to define what the terms we need to solve the problem are. Since first we know about what is an equation; which is referred to the form of converting the real-life problem into mathematical terms, and if it needs to be an equation that it must contain the symbol like $ = $(equals to) and these symbols will represent the same value of two expressions in the algebraic terms like; $a + b = c$
Complete step-by-step solution: We can also say that equations as the common terms on the left- and right-hand sides, example $a + b = c \Rightarrow 2 + 3 = 5$ (a refers to two, and b refers to three and adding the algebraic terms we get the result as c is five) The expression means the way the problem is converted into mathematical problems; like two apples and three oranges. And there are many kinds of equations; like linear equations of the degree one equations also called straight-line equations, quadratic and exponential also the equations with different kinds of degrees. Hence if the equation can be written as in the statement form and that will contain two expressions like a and b with the variables or numbers are called as the equal. The left hand side and right-hand side equations are the same as we discussed above. Since the equation can be rewrite into real life and real-life problems can be written as the equation format only to get the solution as simple as it can.
Note: There are no equations with two expressions that are different only if resultant expressions may not occur the values like $a \ne b$ here a and b are unknown so that we cannot be sure they are equal and also there are no two expressions like above.
