Step-by-step explanation:
The value of a is gotten from the equation 5a - 4 = 3a + 14 which gives a = 9
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
An independent variable is a variable that does not depend on other variables while a dependent variable is a variable that depends on other variables.
Y is between X and Z, hence:
XZ = XY + YZ
XY= 3a, XZ=5a-4, and YZ = 14, therefore substituting gives:
5a - 4 = 3a + 14
a = 9
The value of a is gotten from the equation 5a - 4 = 3a + 14 which gives a = 9
