Question

What is the answer to this stupid thing 5.1y + 21.3 = –0.3y – 24.6

Answer 1

5.1y + 21.3 = -0.3y - 24.6

get the equation to one side and have so it y is positive

5.4y + 45.9= 0

Then subtract 45.9 to the 0 so it's like this

5.4y = -45.9

then divide -45.9/5.4

answer y= -8.5

Answer 2

Answer: y = -8.5

Explanation:

 5.1y + 21.3 = -0.3y - 24.6

+0.3y             +0.3y          

5.4y + 21.3 =           -24.6

          -21.3             -21.3

5.4y           =           -45.9

÷5.4                        ÷5.4  

      y           =          -8.5
