Answer:
Multiple the first equation by -1
Step-by-step explanation:
After doing this you add the two equations together and follow the systems of equations as normal
Therefore y = 2
Angle 1 and angle 2 are a linear pair, which make a sum of 180
angle 2=180-angle 1=180-70=110
20x^2+50 = -40x^2+110x [ Taking x as the unknown positive integer ]
