Can someone help with this q3

AC=20

Step-by-step explanation:

6y+2 = -y+23

move y to one side

7y+2=23

move 2 to the other side

7y=21

divide by 7 on both sides to isolate y

y=3

Substitute y in

-3+23=20

Check your work,18+2=20

answer: sorry

step-by-step explanation: can you tell me pls how to find the rational of two integers

step-by-step explanation:

y = | -2(-2) |     →     y = | 4 |     →     y = 4       ⇒   (-2, 4)

y = | -2(-1) |     →     y = | 2 |     →       y =   2       ⇒   (-1, 2)    

y = | -2(0) |     →     y = | 0 |     →       y = 0         ⇒   (0, 0)

y = | -2(1) |   c →     y = | -2 |     →     y =   2         ⇒   (1, 2)    

y = | -2(2) |     →     y = | - 4 |     →     y =   4         ⇒   (2, 4)
