*To be answered step by step*

Answer 1

Step-by-step explanation:

3x-7=15

3x=22

x=22/3

4x/3+5/5=8

8x+15x

-------@@@=8

6

23x=8*6

23x=48

x=48/23

Answer 2

A) 3x - 7 = 15

:. 3x = 15 + 7

:. 3x = 21

:. x = 21/3

:. x = 7

B) 4x / 3 + 5 / 2 = 8

:. 4x / 3 = 8 - 5 / 2

:. 4x / 3 = ( 16 - 5 ) / 2

:. 4x / 3 = 11 / 2

:. 4x = ( 11 / 2 ) 3

:. 4x = 33 / 2

:. x = 33 / 4 * 2

:. x = 33 / 8
