Answer:
x = 65
Step-by-step explanation:
Complete question is:
Which is the correct solution?
x = 1.8
x = 2.6
x = 45
x = 65
SOLUTION:
The given equation is : [tex]\frac{x}{5}-2=11[/tex]
Substituting all the values of 'x' one by one
-> For x = 1.8 : [tex]\frac{1.8}{5}-2=11[/tex]
-1.64≠11
-> For x = 2.6 : [tex]\frac{2.6}{5}-2=11[/tex]
-1.48≠11
-> For x = 45 : [tex]\frac{45}{5}-2=11[/tex]
7≠11
-> For x = 65 : [tex]\frac{65}{5}-2=11[/tex]
11=11
Therefore, by substituting x in every equation, x = 65
Answer:
Substitute 7 for a.
Simplify the equation after substituting the value for a.
Verify that a = 7 is correct when the result is a true statement.
Step-by-step explanation:
Here, the given equation is,,
And, after solving it the result is,
a = 7
We can check whether a result is the solution of an equation by substituting the result in the given equation.
If we get a true statement, then the result is the solution of the equation.
Thus, for verifying the solution, steps are as follow,
Step 1 : Substitute 7 ,
-9(7-5) = -18
Step 2 : Simplify the equation after substituting the value of a
-9(2) = -18
Step 3 : Verify that a = 7 is correct when the result is a true statement.
-18 = -18
