Answer:
x = -9
Step-by-step explanation:
To solve these types of questions,
a). If both the sides of the equation are different,
2x + 3 = 3x - 6
There will be exactly one solution.
b). If the coefficient of variable 'x' is same in both the sides of the equation,
x - 3 = x - 6
Solution set will be 'none'.
c). If both the sides of the equation are exactly same then equation will have infinite solutions.
2x + 3 = x + x + 3
In the given equation,
6x - (5x + 5) = -8 - 2(x + 12)
Further simplify the equation,
(6x - 5x) - 5 = - 8 - 2x - 24
x - 5 = -2x - 32
x + 2x = 5 - 32
3x = -27
x = -9

Answer : The greatest number of red marbles is 24.
Explanation:
Let the number of red marbles be x
Let the number of blue marbles be y
Since we have given that sum of blue and red marbles is atmost 36
i.e. x+y ≤ 36 (Equation 1)
and we have also given that red marbles is twice of blue marbles .
i.e. x= 2y ( Equation 2)
By putting the value of x from( Equation 2) in ( Equation 1) ,
we have,
2y+y ≤ 36
⇒ 3y ≤ 36
⇒ y ≤
⇒ y≤ 12
Now, we put the value of y in Equation 1
x+ 12 ≤ 36
⇒ x ≤ 36-12
⇒ x ≤ 24
So the greatest number of red marbles are in the bags is 24 .
Y=10 and 3x+2y=3
X=-3 is NOT a function because it has multiple y values for one x value.
Y equals ten is a horizontal line, and passes the vertical line test, as does the third equation
