Question

Plzz help me solve this 1. x/3+x/2=5 2. -6p-9/3=2p+9/5 3. 3y-5/5-2(y-5)=y-1/2 Plzz help I will mark as brainliest

Answer 1

Step-by-step explanation:

(1) x/3 + x/2 = 5

take LCM of denominator we get = 6

2x + 3x/6 = 5

5x = 30

x = 6

(2) -6p - 9/3 = 2p + 9/5

cross multiply we get,

-30p - 45 = 6p + 27

-36p = 72

p = -2

(3) 3y - 5 / 5 - 2y + 10 = y - 1/2

3y - 5/5 - 2y = y - 1/2

cross multiply we get

6y - 10 = 5y - 5 - 2y^2 - 2y

6y - 10 = 3y - 5 - 2y^2

2y^2 + 3y - 5 = 0

2y^2 - 2y + 5y - 5 = 0

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

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

y = 1, -5/2

hope it helps.
