Answer:
[tex]y = \frac{-1}{9}[/tex]
Step-by-step explanation:
[tex]7y + 4 = 3 - 2y[/tex]
add [tex]2y[/tex] to both sides
[tex]7y + 4 + 2y = 3 -2y + 2y \\9y + 4 = 3[/tex]
add [tex]-4[/tex] to both sides
[tex]9y + 4 -4 = 3 - 4 \\9y = -1[/tex]
divide both sides by [tex]9[/tex]
[tex]\frac{9y}{9} = \frac{-1}{9} \\[/tex]
[tex]y = \frac{-1}{9}[/tex]
