Answer 1

Answer:

y = 0.3

Step-by-step explanation:

Solve for y:

$\longrightarrow$ (3.2y - 1.8) - (5.2 y + 3.4) = -5.8

-(5.2y + 3.4) = -5.2y - 3.4:

$\longrightarrow$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):

$\longrightarrow$ (3.2y - 5.2y) + (-1.8 - 3.4) = -5.8

3.2y - 5.2y = -2 y:

$\longrightarrow$ -2y + (-1.8 - 3.4) = -5.8

-1.8 - 3.4 = -5.2:

$\longrightarrow$ -5.2 - 2y = -5.8

Add 5.2` to both sides:

$\longrightarrow$ (5.2 - 5.2) - 2y = 5.2 - 5.8

5.2 - 5.2 = 0:

$\longrightarrow$ -2y = 5.2 - 5.8

5.2 - 5.8 = -0.6:

$\longrightarrow$ -2y = -0.6

Divide both sides of -2y = -0.6 by -2:

$\longrightarrow$ $\sf \dfrac{-2}{-2}y = \dfrac{-0.6}{-2}$

$\sf \dfrac{-2}{-2} = 1:$

$\longrightarrow$ $\sf y = \dfrac{-0.6}{-2}$

$\sf \dfrac{-0.6}{-2} = 0.3:$

$\longrightarrow$ y = 0.3
