Answer:
Step-by-step explanation:
Henry is 3 more than twice Nicholas' age. You can write this as :
H = 3 + 2N
Marcus is 9 less than 6 times Nicholas' age:
M = 6N - 9
Since Henry and Marcus are twins, this means H = N.
3 + 2N = 6N - 9
Add 9 to both sides
12 + 2N = 6N
Subtract 2N from both sides
12 = 4N
Divide both sides by 4 to find N.
N = 12/4 = 3
Answer:
7892 = 7900
472 = 500
Step-by-step explanation:
-1/2 (t+3) -10 = -6.5
t = - 10
(2x - y = -2)2
5x - 2y = -7
4x - 2y = -4
Subtract both
x = -3
5(-3) - 2y = -7
-15 - 2y = -7
-2y = 8, y = -4
Solution: (-3,-4)
