Answer:
<h2><u><em>
n = 1/5m + (-2)/5</em></u></h2>
Step-by-step explanation:
-m + 5n = -2, for n
-m + 5n = -2
-m +5n + m = -2 + m
5n = m - 2
5n/5 = (m-2)/5
n = 1/5m + (-2)/5
PN = PM
6x + 1 = 10x - 17
Add both sides 17
6x + 1 + 17 = 10x - 17 + 17
6x + 18 = 10x
Subtract both sides 6x
6x - 6x + 18 = 10x - 6x
18 = 4x
Divide both sides by 4
18 ÷ 4 = 4x ÷ 4
9/2 = x
x = 9/2
___________________________
QN = 2x + 5
QN = 2 × ( 9/2 ) + 5
QN = 9 + 5
QN = 14
For number 11, Cameron is wrong because 4x isn't a negative.
this is the answer is -10 not sure tho
Add 4 of both sides leaving you with
3/2x=20
Then multiply both sides by 2/3 giving you x=3
