The answer is n = -4. To get that, is to multiply the whole thing by 2 and then solve.
2×(n/2) + 5=3
(Canceled out the 2) n +10 = 6
N = -4 (by subtracting 10)
Answer:
third option I believe.
Step-by-step explanation:
Answer is 14x
Step by step
2x + 5 = 10 - 3x
Let’s start with 2x + 5 = 7 and you bring the x with you which is 7x
Now you do 7x = 10 - 3x , equal sign is plus am guessing and then 10 - 3x is 7x so
7x + 7x = 14x
Answer:
Step-by-step explanation:
So we have : c + 2.5 < 4.3
And it's asking whether c = 1.8 is a solution.
Substitue c = 1.8 in, we get :
1.8 + 2.5 < 4.3
4.3 < 4.3 (not true)
So, c = 1.8 is NOT a solution.
Distribute 7 to 3x and -2, and 4 to x and 5
7(3x - 2) = 21x - 14
4(x + 5) = 4x + 20
Combine like terms
21x + 4x = 25x
-14 + 20 = 6
25x + 6 is your answer
hope this helps
