Answer 2

Hello, this is not the exact question, but this shows you the exact steps on how to complete this problem. :D

Simplifying
2[7 + -5(1 + -1n)] + 5n = -18 + 4[6(n + 1) + -3n]
2[7 + (1 * -5 + -1n * -5)] + 5n = -18 + 4[6(n + 1) + -3n]
2[7 + (-5 + 5n)] + 5n = -18 + 4[6(n + 1) + -3n]

Combine like termsAd by save keep: 7 + -5 = 2
2[2 + 5n] + 5n = -18 + 4[6(n + 1) + -3n]
[2 * 2 + 5n * 2] + 5n = -18 + 4[6(n + 1) + -3n]
[4 + 10n] + 5n = -18 + 4[6(n + 1) + -3n]

Combine like terms: 10n + 5n = 15n
4 + 15n = -18 + 4[6(n + 1) + -3n]

Reorder the terms:
4 + 15n = -18 + 4[6(1 + n) + -3n]
4 + 15n = -18 + 4[(1 * 6 + n * 6) + -3n]
4 + 15n = -18 + 4[(6 + 6n) + -3n]

Combine like terms: 6n + -3n = 3n
4 + 15n = -18 + 4[6 + 3n]
4 + 15n = -18 + [6 * 4 + 3n * 4]
4 + 15n = -18 + [24 + 12n]

Combine like terms: -18 + 24 = 6
4 + 15n = 6 + 12n

Solving
4 + 15n = 6 + 12n

Solving for variable 'n'.

Move all terms containing n to the left, all other terms to the right.

Add '-12n' to each side of the equation.
4 + 15n + -12n = 6 + 12n + -12n

Combine like terms: 15n + -12n = 3n
4 + 3n = 6 + 12n + -12n

Combine like terms: 12n + -12n = 0
4 + 3n = 6 + 0
4 + 3n = 6

Add '-4' to each side of the equation.
4 + -4 + 3n = 6 + -4

Combine like terms: 4 + -4 = 0
0 + 3n = 6 + -4
3n = 6 + -4

Combine like terms: 6 + -4 = 2
3n = 2

Divide each side by '3'.
n = 0.6666666667

Simplifying
n = 0.6666666667

Answer 3

I've used PEMDAS, but keep getting the wrong answer

Answer 4

Umm...That isn't the right answer...(I do know that this question is different.) @jessicaaaaaray! Give me some time to solve it on my end..Then I'll show you how...If this is a multiple choice question with choices abcd....Share them with me here..

Answer 5

I'm sorry it's not multiple choice. Thank you though!

Answer 6

Ok. Before I start typing this out..I'll let you know this might take a while...sorry..:(

Answer 7

Thank you though!

Answer 8

2[7-5(1-n]+5n=-6+2[6n+1-3n]
2[7-5+5n]+5n=6+2[3n+1
2[2+5n]+5n=6+6n+2
4+10n+5n=-6+6+3 --------Combine variables on both sides!
4+15n=-4+6n -------Now let me ask you to solve it from there. Can you?

Answer 9

Yeah, I got it.
2/9 ?
