Answer:
68
Step-by-step explanation:
70+2-4= 68
Answer:
The solution would be (5, -2)
Step-by-step explanation:
To use this method, start by multiplying the second equation by -1. Then add the two equations together.
9x + 5y = 35
-2x - 5y = 0
------------------
7x = 35
x = 5
Now that we have the value of x, use it to solve either equation for y.
2x + 5y = 0
2(5) + 5y = 0
10 + 5y = 0
5y = -10
y = -2
Answer:
10= 1 , 2 , 5 and 10
Step-by-step explanation:
Those are the factors of 10
20+20+38+38=116
116×22 = 2552
