Answer:
y = 4
Step-by-step explanation:
2[2y-1]+5=19 (by PEDMAS, distribute parentheses first)
(2)(2y) - (2)(1) + 5 = 19
4y - 2 + 5 = 19
4y +3 = 19 (subtract 3 from both sides)
4y = 19 - 3
4y = 16 (divide both sides by 4)
y = 16/4
The answer to your question is y = 4
2(2y - 1) + 5 = 19
Subtract 5 in both sides
2(2y - 1) + 5 - 5 = 19 - 5
Simplify
2(2y - 1) = 14
Divide both sides by 2
2(2y - 1)/2 = 14/2
2y - 1 = 7
Add 1 to both sides
2y - 1 + 1 = 7 + 1
2y = 8
Divide by 2 both sides
2y/2 = 8/2
