Question

1. 4(2y-3)=4y+10
y=......


2. 4(2y+3)-2y=3(4y+3)

Answer 1

1. 4y = 22
y = 5,5

2. 3 = 6y
y = 1/2

Answer 2

1. 4(2y - 3) = 4y + 10
8y - 12 = 4y + 10
8y - 4y = 10 + 12
4y = 22
y = 22/4 -> y = 11/2 -> 5 1/2
2. 4(2y + 3) - 2y = 3(4y + 3)
8y + 12 - 2y = 12y + 9
8y - 2y - 12y = 9 - 12
6y - 12y = -3
-6y = -3
y = -3/-6 -> y = 1/2
