Answer: look below
Step-by-step explanation: Coefficient: It is a numerical factor that multiplies a variable in an algebraic expression. Coefficients are used to determine the magnitude of a particular term in an equation or formula.Example: In the equation 2x + 3 = 7, the coefficient of x is 2.Equation: It is a statement that shows the equality between two expressions containing variables and constants. Equations can be solved by finding the value(s) of the variable(s) that make both sides of the equation equal.Example: The equation y = 2x - 5 represents a line on a coordinate plane where every point (x,y) satisfies this equation.Variable: It is a symbol or letter that represents an unknown value in an expression or equation. Variables are used to solve problems and find solutions for different scenarios.Example: In the expression 4a - b, 'a' and 'b' are variables representing unknown values.
