First, you can distribute the -2 to 1 - 7n
the new equation is 5n + 34 = -2 + 14n
then, you can add 2 to both sides to cancel the -2 on the right
now you have 5n + 36 = 14n
after this, you add -5n to both sides, again, to cancel the 5n on the left
you are left with 34 = 9n
lastly, divide both sides by 9 to find the value of n, which is 4.
Answer:
B
Step-by-step explanation:
Lets start solving until we get stuck,
6|x|+25=15
Subtract 25 from both sides
6|x|+25-25=15-25
Subtract
6|x|=-10
Divide both sides by 6
6|x|/6=-10/6
Divide
|x|=-10/6
We get stuck here, we need x to be negative but we cant have a negative x since we have absolute value. This means the answer is b.
Answer:
x<_-2 ( x is less than or equal to -2)
Step-by-step explanation:
First remove opposites and collect like terms so it will be -4x+12+4x<_-8x-8x-20.
Then move them to be 12<_-16x-20.
Move -16x to the left and the 12 to the right to combine it with -20 to become -32.
You are now left with 16x<_-32.
Divide both sides by 16 to get x<_-2.
Hope this helped :) btw <_ is less than or equal to i just dont know how to put the sign on top of the underscore :/
-5 + 9 = 4
-5 - 9 = -14
4 and -14 are both 9 units from -5 on a number line
Opposite angles are equal so the equation is
x + 71 = 108 (A)
