Answer:
x = (1 - yz)/(y- 1)
Step-by-step explanation:
I assume that you meant x = (x+1)/(y+z) because you cannot find x in "x = x + 1/y + z."
Anyways, here is my explanation:
1. Multiple (y + z) on both sides
xy + yz = x + 1
2. Subtract x and yz on both sides
xy - x = 1 - yz
3. Factor x
x(y - 1) = 1 - yz
4. Divide y - 1 on both sides
x = (1 - yz)/(y- 1)
