-5n+4n-7=8
What is the answer for n and how do you solve it
Answer:
-15
Step-by-step explanation:
First combine like terms, aka the variables
-5n+4n-7=8
-1n-7=8
Then, isolate the variable by adding 7 to both sides
-1n-7+7=8+7
-1n=15
Finally, solve by dividing both sides by -1
-1n/-1=15/-1
n=-15
Answer:
n = -15
Step-by-step explanation:
I'll try my best to explain how I solved this
Equation:
-5n + 4n -7=8
Add the light terms on each side:
-n -7 =8
Separate the variables from the numbers:
-n = 15
Do the operation necessary to solve it:
n = -15

Answer:
134 degrees
Step-by-step explanation:
the angles in a triangle always add up to 180.
86+48=134
to find the last angle you subtract 180-134
