Respuesta :
4y - 7 = 5 - 2y
Add 2y to both sides.
6y - 7 = 5
Add 7 to both sides.
6y = 12
Divide both sides by 6
y = 2
Add 2y to both sides.
6y - 7 = 5
Add 7 to both sides.
6y = 12
Divide both sides by 6
y = 2
4y-7 = 5-2y+2y+2y
add 2y on both sides
6y-7 = 5+4y
add 7 on both sides
6y-4y=12
2y=12
y=6
add 2y on both sides
6y-7 = 5+4y
add 7 on both sides
6y-4y=12
2y=12
y=6
