Question

2[2y-1]+5=19 what are the solutions?

Answer 1

y = 4

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

y = 4

Answer 2

The answer to your question is y = 4

Explanation:

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

Simplify

2y - 1 = 7

Add 1 to both sides

2y - 1 + 1 = 7 + 1

Simplify

2y = 8

Divide by 2 both sides

2y/2 = 8/2

Simplify

y = 4
