Answer:

Step-by-step explanation:

substitute (1) to (2):
add x to both sides

subtract 5 from both sides


substitute the values of x to (2):

Given ---›
y = -3
&
y = x - 0.8
So,
=> x = y + 0.8
=> x = -3 + 0.8
=> x = -2.2
Therefore, the best approximation for the solution to this system of equations is = (–2.2, –3)
2 to the 12th power should be correct
