<h3>Equations and expressions</h3>
Equations are expressions separated by an equal sign. According to the question, we are to interprete the given statement into an equation.
Given the statement below:
Three more than four times a number is equal to nine less than twice the number. This is expressed as:
4x + 3 = 2x - 9
where "x" is the number
Simplify
4x + 3 = 2x - 9
4x - 2x = -9 - 3
2x = -12
x = -12/2
x = -6
Hence the value of the unknown number from the given expression is -6
