Question

X + 2(y-6) = 0

3x + 4y = 30



2x = 4 + z

6x - 5z = 18



2w + 3x - 13 = 0

x + 5w - 13 = 0

I need this before 2:30.
​

Answer 1

2x - z = 4
6x - 5z = 18
3z - 2w = -18
If u want me to solve them it’s
1. X = -2y + 12
2. x = 10 - 4/3y | for y, y = 15/2 - 3/4x
3. x = 2+ 1/2z | for z , z = -4 + 2x
4. x = 3 + 5/6z | for z , z = - 18/5 + 6/5x
5. W = -3/2x + 13/2 | for x , x = -2/3w + 13/3
6. x = -5w + 13 | w = -1/5x + 13/5
