<span>4x+7=15
First step is to subtract 7 from both sides to get rid of it.
4x + 7 - 7 = 15 - 7
4x = 8
Now all you have to do is divide both sides by 4.
4x/4 = 8/4
x = 2
The answer is x = 2.</span>
Answer:
The expanded form of the expression
is 
Step-by-step explanation:
We need to write expanded form of the expression 
For expansion we will use distributive property of multiplication over addition

Applying above rule:

So, the expanded form of the expression
is 
Answer:
9
Step-by-step explanation:

f(x)= −2/3x + 5
f(-6)= −2/3(-6) + 5
f(-6)= 4 + 5
f(-6)= 9
