Set up the equation 72=2(x-4)+2(x), the answer is x=20
Answer:
x = 8, y = 3
Step-by-step explanation:
3x - 12y = 60
x + 2y = 14
3x - 12y = 60
3x + 6y = 42 (multiply by 3 so the x is the same as the top equation)
6y = 18 (subtract the equations)
y = 18 / 6
= 3
To find x, substitute y into the 2nd equation since it is the simplest so:
x + 2(3) = 14
x + 6 = 14
x = 14 - 6
= 8
y=3/2x + 7/2. This should be your answer. If you need to work let me know! Glade I could help!
Answer:
x = -8 and x = 2
Step-by-step explanation:
The given equation resolves into two:
The solution to the first can be found by subtracting 3:
x = 2
The solution to the second can be found by multiplying by -1, then subtracting 3.
x +3 = -5
x = -8
The solution set is {-8, 2}.
Answer:
8
Step-by-step explanation:
16 = 2^4
24 = 2³ × 3
40 = 2³ × 5
GCF = 2³ = 8
