Answer:
n=3
Step-by-step explanation:
Operation used is division
Answer: 3
to get this you take 10.5 and divide by 3.5 which equals 3
check your answer: 3.5 x 3 = 10.5
the value of n is 3
-2(1-7n)-5n=34
Multiply the bracket by -2
(-2)(1)=-2
(-2)(-7n)=14n
-2+14n-5n=34
-2+9n=34
Move -2 to the other side. Sign changes from -2 to +2.
-2+2+9n=34+2
9n=34+2
9n=36
Divide by 9 for both sides
9n/9=36/9
n=4
