6b + 5
Step-by-step explanation:
We begin by expounding the equation so as to remove the brackets;
2(a -3) + 4b - 2(a -b -3) + 5
2a – 6 + 4b - 2a + 2b + 6 + 5
Then we put the like terms together;
2a – 2a + 4b + 2b – 6 + 6 + 5
Now when the equation is simplified will look like this;
= 6b + 5

Answer:
42
Step-by-step explanation:
Let total no. of trees be 'X'
Lemon are (1/6) of X = X/6
Orange are (1/2) of X = X/2
Difference is 14
X/2 - X/6 = 14
Lcm is 6
(3X-X)/6 = 14
2X = 14×6
X = 42
Answer:
x = -3
Step-by-step explanation:
Answer: 3 Y=3
Step-by-step explanation:
Y×3=9
3×3=9
You can also check this by rearranging it and dividing 9 by 3.
9÷3=3.
This works for any similar problem.
Example:
Y×4=12 Y=? Y=3
Rearrange it and divide 12 by 4.
12÷4=Y
12÷4=3
So Y×4=12 because 3×4=12
Hope this helps!
Answer: k = -1/3
Step-by-Step Explanation:
=> 3x - 2ky + 4 = 0
Value of ‘x’ = -2
Value of ‘y’ = 3
Substitute values of ‘x’ and ‘y’ :-
=> 3x - 2ky + 4 = 0
= 3(-2) - 2k(3) + 4 = 0
= -6 - 6k + 4 = 0
= -6k = 6 - 4
= -6k = 2
= k = 2/-6
=> k = -2/6 = -1/3
Therefore, k = -1/3
