Question

-12 = -5 - 6n + 11

Answer 1

Isolate n first.
6n = 11 + 12 - 5 Simplify this..
6n = 18 Now we can solve for n by dividing by 6, we get:
n = 18/6 This is equivalent to..
n = 3

Answer 2

can i take you to school with me everyday

Answer 3

Haha that would be nice wouldn't it?

Answer 4

t + 10 - 4t = -11

Answer 5

lol i would never fail a math class again

Answer 6

Keep in mind the ultimate goal is always to get the variable on it's own side of the equation. First we can combine like terms (t - 4t):
-3t + 10 = -11 Now we simplify..
-3t = -21 We have to get t on it's own, remember? So next we divide by -3.
t = 7

Answer 7

8 = 8p + 13 - 3p

Answer 8

First combine like terms, notice that 8p and -3p both have the same variable so we combine them to get:
8 = 5p + 13 Next you can just isolate p by subtracting 13 from both sides. (remember anything we do to one side of the equation we have to do to the other side as well)
-5 = 5p Divide both sides by 5 to get...
p = -1

Answer 9

4y - 16 + 8y = -4

Answer 10

Combine like terms:
12y - 16 = -4 Now we need to isolate y, we do that by adding 16 to both sides (to cancel the -16 out) We get:
12y = 12 Think you can take it from here?

Answer 11

keep going

Answer 12

y = 1. You always want to solve for y with a coefficient of 1, so to get rid of the 12 in 12y we divide the whole equation by 12. \[\frac{ 12y }{ 12 } = \frac{ 12 }{ 12 }\] If you simplify that you get y = 1. Does that make sense?

Answer 13

how much can i buy you for

Answer 14

I'm here for a little longer, so free! I hope this is making sense. If you need a better explanation let me know.
