Answer:

y = -2/5 or y = 1

Step-by-step explanation:

5y^2 - 2 = 3y

5y^2 - 3y - 2 = 0

(5y + 2)(y - 1)

5y + 2 = 0 or y - 1 = 0

5y = -2 or y = 1

y = -2/5 or y = 1

Answer:

y = -2/5 or y = 1

Step-by-step explanation:

5y²-2 = 3y

Add -3y on both sides

5y²- 3y -2 = 0

Factorize.

(5y + 2)(y-1) = 0

(5y+2) = 0

Subtract 2 on both sides.

5y = -2

Divide 5 into both sides.

y = -2/5

(y - 1) = 0

Add 1 on both sides.

y = 1

P + q = 1000 p is 150 greater than q calculate numbers p &amp; q
erma4kov [3.2K]
Because p is 150 greater than q we can substitute p like p = 150 + q. 
When we plug this in it looks like this
(150 + q) + q = 1000
subtract 150 from the left side
q + q = 850
2q = 850
divide 2 to get q alone
q = 425
