Answer 1

rewrite the question please

Answer 2

Step-by-step explanation:

1)

k+7=16

Therefore, k=16-7

k=9

2)

3x-2=7

3x=7+2

3x=9

x= 9/3

x=3

3)

3-x=-4

3+4=x

7=x

x=7

6)

5(x+1)=3(2x-1)

5x+5=6x-3

5+3=6x-5x

8=x

x=8

These were the questions i could solve...the rest that i left..plz check the questions again...there were some writing mistakes...
