and why
OpenStudy (mathstudent55):
First, use the distributive property on the left side.
Can you do that?
OpenStudy (anonymous):
im lost
OpenStudy (mathstudent55):
Ok. Let's work on the left side.
Since we can't add x and 1 because they are not like terms, we can simplify the left side using the distributive property.
OpenStudy (anonymous):
okay go on

Here is the distributive property:
\(a(b + c) = ab + ac\)
Here are two examples:
\(2(3 + 5) = 2 \times 3 + 2 \times 5 = 6 + 10 = 16\)
\(5(x + 4) = 5 \times x + 5 \times 4 = 5x + 20\)
OpenStudy (mathstudent55):
Look especially at the second example.
Now we apply that to the left side of your equation.
OpenStudy (anonymous):
okay
OpenStudy (mathstudent55):
\( 4(x + 1) = 4x + 10\)
We use the distributive proerty on the left side to get:
\(4x + 4 = 4x + 10\)
Do you follow so far?

4x+4 = 4x + 10
4 =10 , which is a false inequality
is no solution
OpenStudy (mathstudent55):
Correct.
The next step is to subtract 4x from both sides which gives you
\(4 = 10\)
Since this is a false statement, that means no solution.
You got it!
