Answer:
x¹=-6 x²=0
Step-by-step explanation:
Substitute y =0
Swap sides
Factor expression
Split into possible cases
Solve equation
Since q+d=19, we can re-write this as d=19-q. Using the second equation 0.25q+0.1d=4 we can multiply both sides by 100. So we get 25q+10d=400. So now we can plug d=19-q into 25q+10d=400. So now we get, 25q+190-10q=400. Subtracting both sides by 190, we get 15q=210 and that q=14 plugging that in d=5
