Answer:
10
Step-by-step explanation:
4x=18
(4x)/4=18/4
x=4.5
4(4.5-2)
4(2.5)
=10
The value of the expression 4(x - 2) is 10 if the value of x is 4.5 from the equation 4x = 18 the answer is 10.
What is a linear equation?
It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
It is given that:
4x= 18
The linear equation in one variable:
After solving:
The value of x:
x = 18/4 = 4.5
Plug the value of x in the expression 4(x - 2)
An expression can be defined as the combination of constants and variables with mathematical operators.
= 4(4.5 - 2)
= 4(2.5)
= 10
Thus, the value of the expression 4(x - 2) is 10 if the value of x is 4.5 from the equation 4x = 18 the answer is 10.
