Answer:
y = 0.3
Step-by-step explanation:
Solve for y:
(3.2y - 1.8) - (5.2 y + 3.4) = -5.8
-(5.2y + 3.4) = -5.2y - 3.4:
3.2y - 1.8 -5.2y - 3.4 = -5.8
Grouping like terms, 3.2y - 1.8 - 5.2y - 3.4 = (3.2y - 5.2y) + (-1.8 - 3.4):
(3.2y - 5.2y) + (-1.8 - 3.4) = -5.8
3.2y - 5.2y = -2 y:
-2y + (-1.8 - 3.4) = -5.8
-1.8 - 3.4 = -5.2:
-5.2 - 2y = -5.8
Add 5.2` to both sides:
(5.2 - 5.2) - 2y = 5.2 - 5.8
5.2 - 5.2 = 0:
-2y = 5.2 - 5.8
5.2 - 5.8 = -0.6:
-2y = -0.6
Divide both sides of -2y = -0.6 by -2:
![\sf \dfrac{-2}{-2}y = \dfrac{-0.6}{-2}](https://tex.z-dn.net/?f=%20%5Csf%20%5Cdfrac%7B-2%7D%7B-2%7Dy%20%3D%20%5Cdfrac%7B-0.6%7D%7B-2%7D%20)
![\sf \dfrac{-2}{-2} = 1:](https://tex.z-dn.net/?f=%20%5Csf%20%5Cdfrac%7B-2%7D%7B-2%7D%20%3D%201%3A%20)
![\sf y = \dfrac{-0.6}{-2}](https://tex.z-dn.net/?f=%20%5Csf%20y%20%3D%20%5Cdfrac%7B-0.6%7D%7B-2%7D%20)
![\sf \dfrac{-0.6}{-2} = 0.3:](https://tex.z-dn.net/?f=%20%5Csf%20%5Cdfrac%7B-0.6%7D%7B-2%7D%20%3D%200.3%3A%20)
y = 0.3
