Answer:
x 
-3
Step-by-step explanation:
Make common denominators
- 
Use the numerators only
2x - (3x - 3) 6
Distribute
2x - 3x + 3 6
-x + 3 6
Subtract 3 from both sides
-x 3
x -3
Answer:
{y,x} = {-6,-2}
Step-by-step explanation:
/ Solve equation [2] for the variable y
[2] y = 2x - 2
// Plug this in for variable y in equation [1]
[1] (2x-2) - x = -4
[1] x = -2
// Solve equation [1] for the variable x
[1] x = - 2
// By now we know this much :
y = 2x-2
x = -2
// Use the x value to solve for y
y = 2(-2)-2 = -6
We can simplify across between the 5 and the 50 and also between the 42 and the 3.
