Answer 1

Answer:

a) x=2.5

b)x=-14

c)z=8/11

d)x=(6+y)/9

every number on the right of the equal is called right hand side or R.H.S and every number on the left of the equal sign is known as left hand side or L.H.S

Step-by-step explanation:

a) 4x-9=19

→4x=19-9

→4x=10

→x=10/4

→x=2.5

b)3x-4=2x-18

→3x-2x=-18+4

→x=-14

c) 3z-1/2=6-z

→(6z-1)/2=6-z

→6z-1=12-2z

→6z+2z=12+1

→8z=-11

→z=8/11

d)5(2x)-6=x+y

→10x-6=x+y

→ 10x-x=6+y

→ 9x=6+y

→x=(6+y)/9
