Question

can someone tell me the answer of this and this and this plz

Answer 1

Answer:

X+4/2x-7=4/3

X+4*3)=(2x-7*4)

3x+12=8x-28

3x-8x=-28-12

-5x=16

X=-16/-5

X=16/5

Answer 2

1) x+4/2x-7 = 4/3

by cross multiplication,

4(2x-7)=3(x+4)

8x-28=3x+12

8x-3x=12+28

5x=40

x=8

2)3p/10 + 7 =p/2 +5

3p/10 - p/2 = 5- 7

3p-5p/10 = -2

-2p/10=-2

p/10=1

p=10

3)3y+5/2y+1 = 1/3

3(3y+5)=2y+1

9y+15=2y+1

9y-2y=1-15

7y=-14

y=-2
