Answer:
57,59,61
Step-by-step explanation:
x=middle integer
x+2=odd number above
x-2=odd number below
(x+2)+(x-2)+x=177
3x=177
177/3=x
x=59
59+2=61
59-2=57
Answer:
1. 12x+7
2. x=7
Step-by-step explanation:
1. 4(5x-1)-8x+11=?
multiply 4(5x-1)
20x-4-8x+11
Subtract 8x from 20x which is 12x
then subtract 4 from 11 which is 7
12x+7
Answer:
x = -2, y = 5, z = 7
Step-by-step explanation:
Let these 3 numbers be x, y, and z
x is the first
y is the second
z is the third number.
Then:
x + y + z = 10
2*y - x = 12
x - y + 2z = 7
x = 2y - 12
(2y - 12) + y + z = 10
and
(2y - 12) - y + 2z = 7
so
3y + z = 22
y + 2z = 19
y = 19 - 2z
3*(19 - 2z) + z = 22
57 - 6z + z = 22
57 - 5z = 22
35 = 5z
z = 7
y = 19 - 2*7 = 19 - 14 = 5
x = 2y - 12 = 2*5 -12 = 10 -12 = -2
