Answer:
see explanation
Step-by-step explanation:
Given the 3 equations
3x + 5y + 5z = 1 → (1)
x - 2y = 5 → (2)
2x + 4y = 11 → (3)
Use (2) and (3) to solve for x and y
Multiply (2) by 2
2x - 4y = 10 → (4)
Add (3) and (4) term by term
4x = 21 ( divide both sides by 4 )
x = 
Substitute this value of x into (3)
2 × + 4y = 11
+ 4y = 11 ( subtract from both sides )
4y = 
( divide both sides by 4 )
y = 
Substitute the values of x and y into (1) and solve for z
3 × + 5 × + 5z = 1
+ 
+ 5z = 1
+ 5z = 1 ( subtract from both sides )
5z = - 
( divide both sides by 5 )
z = - 
Solution is
x = , y = , z = -
Answer:
y = -x + 2.
or
x + y - 2 = 0 (Standard form).
Step-by-step explanation:
Its slope (m) is -1 and y intercept (c) is at y = 2.
y = mx + c
So it's:
y = -1x + 2
Standard form is:
x + y - 2 = 0.
I'm not sure what you mean by General Form.

Answer:
x = y - 2 / 2
Step-by-step explanation:
y = 2x + 2
2x + 2 = y
2x = y - 2
x = y - 2 / 2
