Pls answer tomorrow is my test​

Answer 1

Answer:

1/) x+(x+1) =21

2) 10-2x=2

3) (1/8x)+6=8

4) 2x/5=6

Answer 2

Answer:

i)Let the two consecutive numbers be x,x+1

Step-by-step explanation:

Their sum =21

This implies x+x+1=21

2x+1=21

2x=21-1=20

x=20÷2=10

x=10

x+1=11

ii)Let the number be x

Twice the number=2x

2x subtracted from 10 gives 10-2x

Result=2

This implies 10-2x=2

2x=2-10=-8

-x=-8/4=-4

-x=-4

x=4
