Answer:
Given the equations:
.....[1]
....[2]
Substitute the value of x in [1] we get;'
Use identity:
Combine like terms;
Subtract 36 from both sides we get;
By zero product property, we get;
y = 0 and
Substitute these y values in [2] to get x values;
For y = 0 we have;
x = 2(0) +6 = 0+6 = 6
For x = -4.8
x = 2(-4.8)+6 = -9.6 + 6 = -3.6
Therefore, the solution for the given equations are; (6, 0) and (-3.6, -4.8)
