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
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
