Answer 1

Answer:

A. 7y-5

0 -> y=0

7y- 5

7*0-5

0-5

= -5

1-> y=1

7y-5

7*1 - 5

7-5

=2

2-> y=2

7y-5

7*2 -5

14-5

=9

3-> y=3

7y-5

7*3-5

21-5

=16

4-> y=4

7y-5

7*4-5

28-5

=23

5-> y=5

7y-5

7*5-5

35-5

=30

The solution of 7y-5=23 is y=4

B. 3p+2

1-> p=1

3p+2

3*1+2

3+2

=5

2-> p=2

3p+2

3*2+2

6+2

=8

3-> p=3

3p+2

3*3+2

9+2

=11

4-> p=4

3p+2

3*4+2

12+2

=14

5-> p=5

3p+2

3*5+2

15+2

=17

6-> p=6

3p+2

3*6+2

18+2

=20

The solution to 3p+2=11 is p=3
