Answer:
x+38
Step-by-step explanation:
ok so try to understand my explaination!
it goes by simplifying one by one :)
(18*2+6x+5)+(3*2-5x-9)
(41+6x)+(-3-5x)
41+6x-3-5x
41-3=38
6x-5x=(1)x
x+38
try to understand, im not amazing at explaining :)

hope this helps :-)
Answer:
Option (3)
Step-by-step explanation:
For a geometric progression,
First term of the progression = a
Common ratio of each successive term to the previous term = r
Recursive formula for geometric progression will be,
And 
Following this rule for the G.P. given in the question,
Therefore, from the recursive formula,
Common ration 'r' = -(1.5)
Option (3) will be the correct option.
First equation: 9x + 7y = 1
Second Equation: -3x + y = 13
Multiply the second equation by 3
-3x + y = 13 * 3 = -9x +3y = 39
Now add the first and multiplied second equation together:
10y = 40
Divide both sides by 10:
y = 4
Now you have a value for y, replace y in the first equation and solve for x:
9x +7(4) = 1
9x + 28 = 1
Subtract 28 from both sides:
9x = -27
Divide both sides by 9:
x = -3
The solution is (-3,4)
Step-by-step explanation:
x-5 < -3
or, x < -3 +5
or, x < 2
Now,
x +8 >2
or, x >2 - 8
or, x >-6
