Answer:
y = 3
Step-by-step explanation:
2y - 3 =
square both sides to remove sqrt bracket
(2y - 3)^2 = ( )^2
simplify both sides
(2y - 3)(2y - 3) = - 10y + 12
- 12y + 9 =
- 10y + 12
bring all value to left side
- 2y - 3 = 0
factor
(y - 3)(y + 1)
solve for y
y = 3, y = -1
When plugged back into the equation, only y = 3 is true
