. Which equation has y=5.1
HELP IM CLUELESS

A

Step-by-step explanation:

Isolate the variable y in each equation

A.

y + 2.9 = 8

To isolate y, subtract both sides by 2.9

y = 5.1

This equation has y = 5.1

Let's check the other equations just to get a better understanding of how to do it

B.

y - 11 = 5.1

To isolate y, add both sides by 11

y = 16.1

This equation does not have y = 5.1

C.

y + 4.2 = 5.2

To isolate y, subtract both sides by 4.2

y = 1

This equation does not have y = 5.1

D.

24 - y = 19.2

To isolate y, subtract both sides by 24

-y = -4.8

To isolate y, divide both sides by -1

y = 4.8

This equation does not have y = 5.1

Step-by-step explanation:

Y+2.9=8

8-2.9= 5.1

Y=5.1
