Given :-

a² - 2a - b² = 0
2b + 2ab = 0

To find :-

Value of a and b .

Solution :-

Taking second equation:-

2b + 2ab = 0
2b ( 1 + a ) = 0
2b = 0 or (1+a) = 0
b = 0 , a = -1

Substitute in first equation :-

a² - 2a - b² = 0

When b = 0 ,

a² - 2a - 0² = 0
a² - a = 0
a( a -1) =0
a = 0 , 1

When a = -1 ,

(-1)² - 2*(-1) - b² = 0
1 + 2 - b² = 0
b² = 3
b = ±√3

Answer :-

a = 0,1 ; b = 0
a = -1 , b = ±√3

Solve for w: -4u-w = u+6w

wlad13 [49]

Answer:

Step-by-step explanation:

-4u - w = u + 6w

-4u = u + 7w (Add w to both sides)

-5u = 7w (Subtract u from both sides)

w = $-\frac{5u}{7}$ (Divide both sides by 7)
