Answer 1

Answer:

1) 7/3, 2) x= 40/3, 3) Number= -1/2

Step-by-step explanation:

1) 2y + 5/3= 26/3-y

2y+y = 26/3-5/3

3y= 21/3 ⇒ y= 21/3*1/3

∴y= 7/3

2) 2x+1/3= 7x/15+ 3

2x+1/3-7x/15= 3

since LCM of 3 and 15 is 15 we multiply 2x+1 with 5

10x+5-7x/15 = 3

3x+5/15= 3

3x+5= 45

3x= 40 ⇒x= 40/3

3) let the number be x

when multiplied by 5/2 it becomes 5x/2

according to the question,

5x/2+ 2/3= -7/12

5x/2= -7/12-2/3

5x/2= -7-8/12= -15/12= -5/4

x= -5/4* 2/5= -2/4= -1/2
