PLEASE SOLVE FOR Y: <img src="https://tex.z-dn.net/?f=7y%2B4%3D3-2y" id="TexFormula1" title="7y+4=3-2y" alt="7y+4=3-2y" align="a

Answer:

$y = \frac{-1}{9}$

Step-by-step explanation:

$7y + 4 = 3 - 2y$

add $2y$ to both sides

$7y + 4 + 2y = 3 -2y + 2y \\9y + 4 = 3$

add $-4$ to both sides

$9y + 4 -4 = 3 - 4 \\9y = -1$

divide both sides by $9$

$\frac{9y}{9} = \frac{-1}{9} \\$

$y = \frac{-1}{9}$
