An equation is formed when two equal expressions. An equation is formed of two equal expressions. The value of the expression 4x+9 is 16.
An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
Given the equation 17=3+8x, solving the equation for x as shown below. The value of x in the equation is,
17 = 3 + 8x
17 - 3 = 8x
14 = 8x
x = 14/8
x = 1.75
Now, substitute the value of x in the expression 4x+9, therefore, the value of the expression 4x+9 is,
4x + 9
= 4(1.75) + 9
= 7 + 9
= 16
Hence, the value of the expression 4x+9 is 16.
