Answer: y = (1/2)x + 2
Explanation
X is between 80 and 90, if the square root of a number (x) is 9, you would do 9x9 to solve for x, x=81
Answer: 2,3,8
Step-by-step explanation:
if,
x+y+z=13
2x+5y+6z=67
5x-y=7
Solve [x+y+z=13 2x+5y+6z=67] to find: -3x+z=2 and keep
|
x+y+z=13
5x-y=7
6x+z=20 and -3x+z=2
z=8
x=2
y=3
