Answer:
x=9, y=3
Step-by-step explanation:
-4x+6y=-18
y=-2x+21
-4x+6(-2x+21)=-18
-4x-12x+126=-18
144=16x
x=9
y=-2x+21
y=-18+21
y=3

Answer:
Solution is : x = 1 ± 0.5√3
Step-by-step explanation:
We have given quadratic equation:
4x² - 8x + 1 = 0
We need to find solution using quadratic formula.
i.e x = 
Compare from general quadratic equation ax² + bx + c=0
Here a= 4 , b = -8 and c = 1
∴ x = -(-8)±√((-8)²-4·4·1) / 2·4
x = (8 ±√48 )/8
x = 1 ± 0.5√3 , This is the answer
