x = -1
Step-by-step explanation:


or

Since both sides have the same base, we can write
10x = 5x - 5
or
5x = -5
x = -1
According to the system:
5 – 7x + 2y² = -10
1 – 5x – 2y = -22
______________
a) No ; (4, 6) is not a solution to the
system. This point does not touch either equation.
b) No ; (6, 4) is not a solution to the system. This point does not touch either equation.
Solutions:

x = ( 122 ∓ 3√101 ) / 25 ≈ 3.674 or 6.086
y = ( -7 ± 3√101 ) / 10 ≈ 2.315 or -3.715
Answer:
Step-by-step explanation:
lets solve for x
flip the equation
add-4 to both sides
divide both sides by 3
x=1/3y+-4/3
