Answer:
Step-by-step explanation:
First, use PEMDAS to distribute the -2 to the parenthesis.
Combine like terms on the right side.
Now, you may either subtract the f's or the constants. I'll subtract the constants first, meaning I will add 10 to both sides.
Now subtract the 2f from both sides.
Divide both sides by 10.
Simplify.
Answer:
The value of f:
Step-by-step explanation:
Given the expression
Group like terms
Subtract the numbers: -7-9=-16
Expand: -2(-4f + 5) = 8f - 10
Add 10 to both sides
Simplify
Subtract 2f from both sides
Simplify
Divide both sides by 6
Simplify
Therefore, the value of f:
