Answer:
x=6, x= -5
Step-by-step explanation:
Factor the equation
x^2 - x - 30 = 0 ----> (x-6)(x+5)=0
Next find the solution by setting those in the paranthesis equal to zero.
x-6=0 ----> x= 6
x+5=0 ----> x= -5

Answer:
Step-by-step explanation:
x + z + y = 60
- x + z + y = -6 <-- (x - z = y + 6)
x + 3z + y = 40
<em>cancel out the two equations (z minus each other and y minus each other)</em>
x + z + y = 60
- -x + z + y = -6
